The aim is that if the value isn't found in the registry then I want to assign a default value and then have that value display as the default value in a field in the installer UI. The default value I actually want to use is [ComputerName] but obviously I can't use [ComputerName] directly in the property value attribute because it will give me errors on compiling, specifically:
warning CNDL1077: The 'MYPROPERTY' Property contains '[ComputerName]'
in its value which is an illegal reference to another property. If
this value is a string literal, not a property reference, please
ignore this warning. To set a property with the value of another
property, use a CustomAction with Property and Value attributes.
I want to get it working with plain text before I even try [ComputerName] but so far I can't even get that working.
In my project I have a Product.wxs file which contains the Product element, lots of custom actions (most of which are running fine but they're all running significantly later) and the following elements which are not cooperating and which are all siblings under the Product element.
Property definition and registry search:
<Property Id="MYPROPERTY" Value="ADefaultValue">
<RegistrySearch Id="MyProperty" Type="raw" Root="HKLM" Win64="$(var.Win64)"
Key="Software\MyCompany\MyApplication" Name="MyProperty" />
</Property>
Custom action definition:
<CustomAction Id="SetMyPropertyDefault" Property="MYPROPERTY" Value="MyCustomValue" Execute="immediate"/>
Custom action execution:
<InstallExecuteSequence>
<Custom Action="SetMyPropertyDefault" After="AppSearch"><![CDATA[MYPROPERTY="ADefaultValue"]]></Custom>
</InstallExecuteSequence>
It just will not work for me at all.
For the custom element content I have tried:
<Custom Action="SetMyPropertyDefault" After="AppSearch"><![CDATA[MYPROPERTY="ADefaultValue"]]></Custom>
<Custom Action="SetMyPropertyDefault" After="AppSearch">1</Custom> // I thought this would always run the custom action.
<Custom Action="SetMyPropertyDefault" After="AppSearch">NOT MYPROPERTY</Custom> // Back when I wasn't using the default value on the property at all.
The result is always the same, I'm still getting "ADefaultValue" showing up in the UI, never the alternate "MyCustomValue".
According to every blog and SO post I've seen I'm doing exactly what I should be doing except clearly I'm missing something.
Any ideas?
UPDATE/Answer:
The piece of information that I was missing which was provided by #sutarmin-anton was that InstallUISequence runs before InstallExecuteSequence (seems counter-intuitive to me but there you go).
But as it happened I didn't need to explicitly duplicate the custom action call in each of the install sequence elements, instead I used the SetProperty element.
So now I've got the following in my Product.wxs as children of the Product element:
<Property Id="MYPROPERTY">
<RegistrySearch Id="MyProperty" Type="raw" Root="HKLM" Win64="$(var.Win64)" Key="Software\MyCompany\MyApplication" Name="MyProperty" />
</Property>
<SetProperty Id="MYPROPERTY" After="AppSearch" Value="[ComputerName]">NOT MYPROPERTY</SetProperty>
It now runs the SetProperty after AppSearch in both InstallUISequence and InstallExecuteSequence, but the second time it runs the NOT MYPROPERTY will come out false so it doesn't get reset, and of course if it's run in quiet mode it'll still work correctly.
When you going through installer UI, installation is in InstallUISequence. InstallExecuteSequence runs after all UI events. This is cause of you have not seen "MyCustomValue". To change your property before UI sequence you should place your custom action in "InstallUISequence".
By the way, why don't you set default value of your property to "MyCustomValue"? Then, if AppSearch wont find value in regisrty, it just leave default value that you are trying to set manually.
You may be overcomplicating things. The MYPROPERTY value will not be set at all if you don't set a default. So then you call your CA to set it if 'NOT MYPROPERTY'
I see that you've tried this, and I'd say it's the correct approach that I'd try to diagnose rather than try something else. A verbose log would be invaluable. Do a:
msiexec /i [path to msi] /l*vx [path to a text log file]
and see what CA is called, what AppSearch does, property values etc.
Your original comment of "I can't use [ComputerName] - if that's the problem why not tell us what happened and maybe there is a solution that doesn't require all this. What's the compile error, for example?

What I want to do is copy the value of a single property, and place it as the value of another property. Is this possible with Wix?
<Property Id="PROP1" Value="default" Secure="yes"/>
I want PROP2 to have the same value some where during the UI sequence.
You can use Custom action to accomplish it. Define action as
<CustomAction Id="SetMyProperty" Execute="immediate" Property="PROP2" Value="[PROP1]" />
Then call it in <InstallUISequence> or <InstallExecuteSequence> when you need it set, something like
<Custom Action="SetMyProperty" After="FileCost"></Custom>
Although #Mischo5500 answer is correct, there is a more elegant way to achieve the same. You can use a special element, <SetProperty>, which was designed exactly for that purpose.
The benefits of using it is:
It's just one line of WiX code
It is scheduled properly by default into both sequences
The name of the element is more natural and self-explanatory
Thus, the above example can be transformed into the following:
<SetProperty Id="PROP2" Value="[PROP1]" After="FileCost" />
I have a WiX installer project that I'm creating where I'd like the installer to check to see if another application is already installed on the user's machine. If it is, then I'd like to set the install level of one of the features to "1", otherwise it should remain hidden (i.e. install level = 0). To find out where the application is installed, I first do a registry search:
<Property Id="MYAPPINSTALLFOLDER">
<RegistrySearch Id='InstallPathRegistry'
Type='raw'
Root='HKLM'
Key='SOFTWARE\SomeLongAppPath' Name='FileName'
Win64='yes'/>
</Property>
You'll notice that the registry value that I end up getting is actually the directory of the installed application including the actual program name with extension (let's say myapp.exe). So, once I get the full path of the installed application, I check to see if the file exists:
<Property Id="MYAPPINSTALLED">
<DirectorySearch Id="CheckFileDir" Path="[MYAPPINSTALLFOLDER]" AssignToProperty="yes">
<FileSearch Id="CheckFile" Name="myapp.exe" />
</DirectorySearch>
</Property>
Now, what I would expect to see is that if the file actually exists in that location, then the Property called "MYAPPINSTALLED" would be set to 1, otherwise it would be 0. Then, when I setup my features I use something like this:
<Feature Id="ThirdPartyPlugins" Title="Third Party Plugins" Level="0">
<Condition Level="1">MYAPPINSTALLED</Condition>
<ComponentGroupRef Id="MyAppPlugin" />
</Feature>
However, when I run my installer the third party plugin feature is always hidden. I've enabled msi datalogging by setting the property like this:
<Property Id="MsiLogging" Value="voicewarmupx"/>
And when I check the log file I can definitely see that the MYAPPINSTALLFOLDER property gets changed to the correct file path when it does the registry search. However, if I search the log for the property MYAPPINSTALLED, then I can see the following:
AppSearch: Property: MYAPPINSTALLED, Signature: CheckFileDir
Action ended 15:55:06: AppSearch. Return value 1.
So, it looks like it worked, however it doesn't seem to ever set the Property to equal the search value. Am I doing something wrong? Can someone explain why my feature install level never gets set to 1 even though the application file exists?
Edit
Ok, after more debugging... I think the issue is that the directory search is trying to use a path that includes the file name and extension (i.e. C:/Program Files/MyApp/myapp.exe") instead of just the directory where the file comes from. This is because the registry search has the full path including the file name stored (but not just the install directory). If I do a directory search just using the correct absolute directory (not using the registry search) then the process works. So, my follow up question is... my Property MYAPPINSTALLFOLDER contains the full path with file name and extension. Is there a way to strip the file name and extension from this property so that I just have the proper directory name to search for?
You're checking to see if another application is installed but that's rather a long way around. Also, the file search returns a path, not zero or 1, but either way a full verbose log should tell you if the properties are being set. It might help if you could post the entire log somewhere rather than the parts you think are the only relevant ones. e.g. There's probably an AppSearch in the execute sequence for silent installs.
It's requently easier to do a single search for other applications that were installed with MSI packages in these ways:
If you know the other product's UpgradeCode (and version ranges if applicable) then add Upgrade/UpgradeVersion elements with onlydetect set to yes, and that search will set a property if the product is detected.
If you know (or can find out) the Component id of any of the relevant components from that other product, then you can use them in a WiX ComponentSearch. If you get the target property set then that component is installed. This post contains a couple of ways to find out component guids:
How to find out which application requires a certain assembly from GAC?
It's also puzzling that the AppSearch log extract you posted only refers to one property. The Directory/FileSearch is also an AppSearch, so if the MSI actually contains two searches in AppSearch there should be references to all the properties being set. Again, that's a reason to post the entire log and look in the MSI file for those searches. The RegLocator search is documnented to occur before the DRLocator, so why is there no MYAPPINSTALLFOLDER property in the AppSearch log entry? You're not on a 32-bit system are you? (noticing the win64 search).
Per the WiX documentation:
Use the AssignToProperty attribute to search for a file but set the outer property to the directory containing the file. When this attribute is set to yes, you may only nest a FileSearch element with a unique Id or define no child element [of the DirectorySearch].
I added the text in the brackets to make it more clear.
So, after reading this sentence a few times and cross referencing your WiX XML, I think I see what the problem is with your current WiX XML. You perform a separate registry search from the directory search. Instead, you should nest these. There are two ways to perform the search, depending on what you want to do. One way is to simply retrieve the registry value from the registry, and if the value exists, then you make the assumption that the feature's required application is installed, at which point you appropriately set a property that would enable hiding/showing the feature within your installer's feature selection tree. The other way is to actually find the file you're interested in, using the results of the registry search as the basis for the file search.
Below is the XML for just a registry search, which doesn't check that the file actually exists on disk. You're making the assumption that if this registry value exists, the file is installed and available.
<Property Id="MYAPPINSTALLFOLDER">
<RegistrySearch Id='InstallPathRegistry'
Type='raw'
Root='HKLM'
Key='SOFTWARE\SomeLongAppPath' Name='FileName'
Win64='yes'/>
</Property>
<Property Id="SHOW_APP_FEATURE" Value="hidden" />
<SetProperty Id="SHOW_APP_FEATURE" Value="collapse" Sequence="both" After="CostFinalize">
<!-- If MYAPPINSTALLFOLDER is defined and contains any non-empty value, this
evaluates to TRUE; otherwise, it evaluates to FALSE.
-->
MYAPPINSTALLFOLDER
</SetProperty>
<!-- You could also be more explicit:
<SetProperty Id="SHOW_APP_FEATURE" Value="collapse" Sequence="both" After="CostFinalize">
<![CDATA[MYAPPINSTALLFOLDER <> ""]]>
</SetProperty>
-->
<Feature Id="MyAwesomeFeature" Title="My Awesome App Feature"
Display="[SHOW_APP_FEATURE]">
... <!-- Component/ComponentRefs go here -->
</Feature>
If you want to ensure that, even if the registry value exists in the registry, that the file it points to is 1) actually a file path; and 2) that the file actually exists on disk, then you need to perform a nested file search within a directory search, which itself is nested within a registry search. You would again need to use a SetProperty custom action to set a property that would enable the hiding/showing of the feature within your installer's feature selection tree. Here's the XML for this search:
<!-- Performing a FileSearch nested within a DirectorySearch,
which is itself nested within a RegistrySearch
This search twill ensure that the file exists on disk, and
if so, assign the full filename and path to the
MYAPPINSTALLFOLDER property.
-->
<Property Id="MYAPPINSTALLFOLDER">
<RegistrySearch Id='InstallPathRegistry'
Type='raw'
Root='HKLM'
Key='SOFTWARE\SomeLongAppPath' Name='FileName'
Win64='yes'>
<DirectorySearch Id='InstallPathDirectory' AssignToProperty='yes'>
<FileSearch Id='InstallPathFile' Name='myapp.exe' />
</DirectorySearch>
</RegistrySearch>
</Property>
<Property Id="SHOW_APP_FEATURE" Value="hidden" />
<SetProperty Id="SHOW_APP_FEATURE" Value="collapse" Sequence="both" After="CostFinalize">
<!-- If MYAPPINSTALLFOLDER is defined and contains any non-empty value, this
evaluates to TRUE; otherwise, it evaluates to FALSE.
-->
MYAPPINSTALLFOLDER
</SetProperty>
<Feature Id="MyAwesomeFeature" Title="My Awesome App Feature"
Display="[SHOW_APP_FEATURE]">
... <!-- Component/ComponentRefs go here -->
</Feature>
This should allow you to accomplish what you're trying to achieve.
I've got different installation modes. Depending on the parameters I do things like:
<Property Id="PROP1" Value="Value1" />
<SetProperty Id="PROP1" Before="CostFinalize" Sequence="execute" Value="Value2"></SetProperty>
The problem is that I've got more than 2 options, when I'm adding them I'm getting.
Duplicate symbol 'CustomAction:SetPROP1' found.
Is there a way to have some sort of switch statement or how do you handle multiple conditionals?
Another trouble is, I've got multiple variables set depending on the value (about 10 right now) and it's very cumbersome to list them all with absolutely the same code
<SetProperty Id="PROP2" Before="CostFinalize" Sequence="execute" Value="Value2"></SetProperty>
<SetProperty Id="PROP3" Before="CostFinalize" Sequence="execute" Value="Value3"></SetProperty>
etc
Is there any way to make it like:
<Condition val="...">
<setProperty.../>
<setProperty.../>
<setProperty.../>
</Condition>
Thanks!
First of all, try to re-think the architecture of your installation program. Is it really necessary to set all those properties based on the same condition? Or maybe it's better to "condition"-ize the appropriate features and components in a more plain way?
Let's get back to the technical side of your question. The SetProperty element is just a shortcut which is "all-in-one" solution for defining a custom action which sets a property and scheduling it appropriately. It is true that you can't use it to set the same property to different value, because there's no ID attribute of the SetProperty element itself.
Instead, use the good old style of defining a custom action and scheduling it manually:
<CustomAction Id="SetProp11" Property="PROP1" Value="Value1" />
<CustomAction Id="SetProp12" Property="PROP1" Value="Value2" />
...
<InstallExecuteSequence>
<Custom Action="SetProp11" After="...">your condition here</Custom>
<Custom Action="SetProp12" After="...">your condition here</Custom>
...
</InstallExecuteSequence>
This definitely adds extra typing work and makes your code less readable, but this way you can work your problem around. However, let me emphasize once again - the fact that you have to invent workarounds means that the code starts to smell and it might make sense to re-think it through.
And I'm not aware about the way to set a number of properties in a bunch, like in switch statement. Alternatively, technically you can create a e.g. C# custom action and let it do the job for all the properties at once.
Hope this helps.
I searched through several questions at Stack Overflow, but nothing helped me. The problem is:
I look in the registry for some value (I know how to do that). I know how to set property. But I cannot find the way how to write this expression in WiX. This is what I want to write in pseudocode:
if(registryvalue contains substring1)
set property to value1
if(registryvalue contains substring2)
set property to value2
This condition must be evaluated at runtime. Is there a way to write this condition? What would some sample code look like?
You can use a type 51 custom action to set the property:
<CustomAction Id="SET_VALUE1" Property="TEST_PROPERTY" Value="value1" />
<CustomAction Id="SET_VALUE2" Property="TEST_PROPERTY" Value="value2" />
Use the condition when you call the custom action in install sequences:
<Custom Action="SET_VALUE1" After="AppSearch">Not Installed AND (REG_VALUE="substring1")</Custom>
<Custom Action="SET_VALUE2" After="AppSearch">Not Installed AND (REG_VALUE="substring2")</Custom>
Or you can write the custom actions in managed code like C#, and schedule it after AppSearch in case you have many comparisons.
I want to set a property in a custom action and use it in the standard custom action "util:User" afterwards. But no matter where I put the property in my wxs-file, I always get "error LGHT0094 : Unresolved reference to symbol"
Details:
In my setup I want to add a new user by using util:User. The user should be added to the group "Power Users" by using util:GroupRef. No Problem so far. Unfortunately the group names are language dependent. In german "Power Users" is "Hauptbenutzer". So I want to look up the well known SID S-1-5-32-547 in a custom action, set a property in this custom action by calling MsiSetProperty and then use the property for util:GroupRef.
As far as I understand, the property must be declared somewhere in the wxs-file.
In the examples I found, the property was never declared as follows (but I also tried that):
<Property Id="TextSID" Value="Power Users" />
In the examples there always was a custom action to set the property, like:
<CustomAction Id="SetTextSID"
Property="TextSID"
Value="Power Users"
Return="check" />
My problem is, that the creation of the user fails to "compile" because the property "TextSID" is not known:
<Component Id="CreateUser" Guid="Some GUID here in my original wxs file">
<util:User Id="UserUser"
Name="User" Password="Password"
CanNotChangePassword="yes" PasswordNeverExpires="yes">
<util:GroupRef Id="TextSID" />
</util:User>
</Component>
I have never done a custom action before and I'm a new to WiX and MSI, so any idea would be very welcome.

Ralf
Sorry for wasting your time.
I stared at my XML for hours before I posted this question, just to find the answer immediately after my post :-(
My only problem was, that it is not possible to reference to something that isn't there. In this case the "util:Group" was missing.
