MyApp version 1.0 contained the file foo.dll. The version of this file was version 10.5.567. Now MyApp is version 2.0 and the version of foo.dll is 2.0.123. The version is LOWER than the old version. The vendor who wrote this dll decided to go backwards with the file version number. This is not a decision I can change.
How do I get WiX to always install this file?
The RemoveExistingProducts action is scheduled after the InstallFinalize action and also cannot be changed.
InstallShield had an 'always overwrite' flag but I don't think I can mimic this without changing the behavior of all files via a compiler switch. I do not want this. I just want to update THIS ONE file.
I have also tried
<RemoveFile Id="foo.dll" On="install" Name="foo.dll" />
But this did not work either. I end up getting 'Error 2753 The file foo.dll is not marked for installation' later.
It is really crazy this post is 10 years old and we also have this problem. The other approaches did not work for us.
How to solve it:
All files which should be copied regardless of their version, must be in their own component
Component element must have a unique Guid, not a *
Set KeyPath to no in the inner File element
Example:
<Component Id="cmpExample" Guid="{5ABE7229-C247-4CBA-B8DE-2C4968CD103E}" >
<File Id="fileExample" KeyPath="no" Source="$(var.TargetDir)\SomeExample.dll" />
</Component>
I would recommend to aggregate all those component elements in a component group. And furthermore you can use XML Transformation to get rid of those files if you use heat.exe to harvest all your files.
With this solution you can copy the file, even if the installed file version is higher. And it still works as expected when a higher file version will be installed with your upgrade.
This isn't easy because it is against the standard behaviour of MSI-packages. When compiling, you have to set supress-file-options with -sf in light.exe. Then there are no file-informations from your files read. You can set DefaultVersion this version will be used.
I have also used RemoveFile in a solution, but i can say that it works. I have add it in same componente where i add the file.
<Component>
<File DiskId="1" Id="fooDLL" Name="foo.dll" Vital="yes"
DefaultVersion="$(var.MAJORVERSION).$(var.MINORVERSION).$(var.BUILDVERSION)"
DefaultLanguage="0"></File>
<RemoveFile Id='RemoveOldDLL' On='install' Name='foo.dll'/>
</Componente>
This is not a clean way, but to remove an old version it works for me.
I answered a similar question a while back:
Forcing an upgrade of a file that is modified during its initial installation
I think I would use a companion file to solve this problem, but you might get validation errors since the file in question is a dll and hence considered an executable. I believe it would still work, and reliably so.
Annotation
Force always overwrite in Light.exe output with the "InstallShield trick":
XPath="/wixOutput/table[#name='File']/row/field[5]" InnerText=„65535.0.0.0“
One thing that could be worth trying is to set RemoveExistingProducts real early in the sequence. The MSI should then remove the old program first, then install the upgrade. This will solve your issue. e.g.
<InstallExecuteSequence>
<RemoveExistingProducts After="CostFinalize" />
</InstallExecuteSequence>

I have Wix project in which I need a common used dll library to be installed if it's absent.
If this dll exists I should not overwrite it.
So, when I set DefaultVersion="0.0.0.0" this dll is not overwritten if it exists, its ok. But when I delete app, the dll is beeing removed. How do I prevent removing dll in the case when it existed before installation?
I don't want to make it permanent because it should be removed if it didn't exist before installation.
<Component Id="myLib.dll" Permanent="no" Directory="Shared_Dir">
<File Name="myLib.dll" KeyPath="yes"
Source="mySource\myLib.dll"
DefaultVersion="0.0.0.0"
/>
Add reference to WixUtilExtension and xmlns:util="http://schemas.microsoft.com/wix/UtilExtension" attribute to Wix element in your code.
Define <Property Id="Dll_Installed" Value="false"/> in Product element.
Add child <Condition>NOT Dll_Installed</Condition> to component myLib.dll.
Add that somewhere in your code:
<Fragment>
<util:FileSearch
Id="Dll_Installed"
Variable="Dll_Installed"
Path="[Shared_Dir]myLib.dll"
Result="exists"/>
</Fragment>
DefaultVersion attribute is not necessary.
The feature you are describing is reference counting. The Windows Installer reference counts with Components. Components are identified by their GUID.
So the normal way to address this requirement is to put the File in a Component and make sure the GUID of the Component is stable. The WiX Toolset should do exactly that automatically if if you do not specify the Component/#Guid attribute.
So the default behavior should just work for you.
The only other piece of the puzzle is the Windows Installer will install the latest version of a file. If the file version is the same or less the file will not be installed but will be reference counted.
Based on the details in the question it seems like you should be just fine with:
<Component Directory="Shared_Dir">
<File Source="mySource\myLib.dll" />
</Component>
One might ask why the Windows Installer use Components to reference count files. We'll, it allows you to group other resources, like registry keys, together and control their install as a unit. Much more important if you are installing COM servers than plain old files.
I'm using WiX 3.8 (the latest stable release, I think), and I can't seem to get a config file to not get uninstalled-and-reinstalled during a major upgrade.
There are lots of questions about this on SO -- a lot of answers point to this site as a good answer. However, the suggestion given doesn't work (for me).
What the site says is to place each config file in its own component and mark the file as the key path of the component. Something like this:
<Component Id="config.xml"
Guid="*"
Directory="folder_where_config_file_lives">
<File Id="config_file"
Source="$(var.Project.ProjectDir)bin\Release\configFile.xml"
KeyPath="yes"/>
</Component>
Great. Next it says to schedule RemoveExistingProduct after the InstallFiles action, like so:
<InstallExecuteSequence>
<RemoveExistingProducts After="InstallFiles"/>
</InstallExecuteSequence>
Problem is, when I compile, I get this error:
The InstallExecuteSequence table contains an action
'RemoveExistingProducts' that is declared in two different locations.
Please remove one of the actions or set the Overridable='yes'
attribute on one of their elements.
This person also had that problem, but he seems to have solved it. What fixed it for him was adding a scheduling attribute to the , which effectively got rid of the "two different locations" declaration problem (I guess):
<MajorUpgrade Schedule="afterInstallInitialize"
DowngradeErrorMessage="A newer version of [ProductName] is already installed."/>
So when I substitute the schedule change attribute (which contains a attribute itself, I guess), not only does it not work -- the config file gets removed and replaced during the upgrade -- it causes even more weirdness. My project has a bootstrapper with a lot of MSIs, and although I get log files for the installation of all of the MSIs that are after the MSI that contains the config file, they aren't installed.
Let me repeat that: the logs say that the MSIs are installed, but they aren't. There's probably a rollback somewhere that I can't find in the log files, but reading the MSI log files it looks like the installation went swimminly.
Does anyone know a way for a config file to not be removed-and-reinstalled during a Major Upgrade in Wix 3.8? What I've mentioned above is the best info from the interwebs that I could find, but I've tried pretty much everything on SO to no avail.
The MajorUpgrade element has everything you need, including where the RemoveExistingProducts action is scheduled. Don't add a RemoveExistingProducts into a sequence as well.
RemoveExistingProducts shouldn't be after InstallFiles. It's not clear where that comes from, but the documentation doesn't say that's a choice:
https://msdn.microsoft.com/en-us/library/windows/desktop/aa371197(v=vs.85).aspx
When RemoveExistingProducts is sequenced early (such as after InstallInitialize or InstallValidate) it means that you are effectively uninstalling the old product followed by an install of the new product upgrade, and that means uninstalling the config file and installing the one in the upgrade. The way to retain the config file is to schedule REP afterInstallExecute. This results in an upgrade that is basically a version-rules install of the new product over the older installed one. The version rules mean that if you want updated binaries you must update their file versions. The good news about data files (your config file) is that updated data files won't be replaced:
https://msdn.microsoft.com/en-us/library/windows/desktop/aa370531(v=vs.85).aspx
The older product then gets uninstalled, retaining the resulting set of files.
So sequencing of REP afterInstallExecute in the MajorUpgrade seems to be what you want. A caveat is that you need to follow component rules, which should happen automatically if you have auto-generated * guids in WiX.
IMO, Windows Installer was invented before XML caught on and the component rules don't handle it well. What I prefer to do is to not fight this behavior. Write your application so that one config file is owned by the installer and can always be safely overwritten and another config file that holds your user configuration data and that MSI doesn't know about. This second file should take override the first file.
I have a data file that is installed with my application. When it is installed fresh, the data file gets installed properly. When it is upgrading, it was always overwriting the existing instance of the file, which was not wanted. I added the NeverOverwrite="yes" flag, and now for a new install is still the same, but for an existing install, it is deleting the existing file, and not installing the new file either. Have I used the flag incorrectly? This is the snippet in question:
<Component Id="cmp8553E6DDC92DBCDC568FB76CA13E7AF2" Guid="{C94263EB-56AF-4B19-942F-C92998252932}" NeverOverwrite="yes">
<File Id="fil7C9456E83E3FB4618684509DEEF67EBD" KeyPath="yes" Source="$(var.CDWrapper.ProjectDir)..\foo\bar" />
</Component>
Turns out I didn't have a full understanding of the NeverOverwrite flag and our usage of it. I will have to find a different method to preserve the existing file instead of always installing a new copy, but that's a whole different issue that should have reasonable answers elsewhere.

I am able to make major upgrade with my test.wxs by using app.msm (merge module). But not able to make patch with successful installation. Patch install (update) is reflecting in version change in the "Programs and Features" and showing in "View Installed updates". The manual changes also are reflecting with patch update. But whatever the changes in "app" (which are created app.msm and referred in test.wxs) folder are not reflecting.
I have used 2 approaches for making patch, which are mentioend in below urls
1) http://wixtoolset.org/documentation/manual/v3/patching/patch_building.html
2) http://wixtoolset.org/documentation/manual/v3/patching/wix_patching.html
Please help in this regards.
First, I would advise to find out, whether the built patch contains the correct files or not. If not, you have a build problem, that the msm is not updated. If yes, you have most likely a problem with the content of the msm which may be not consistent with it's predecessor (especially GUIDs, table primary keys, etc.).
You can find out and see the content of the patch without installing with tools like Orca and Insted which you can search and download.
Second, using merge modules is highly complicating things, especially for patches, and of limited usefulness, if they are your own and you use them only once. Msms are primarily made for situations, where you need the .msm at least for 2 different MSI packages. I have seen a handfull of problems using merge modules in patches with other tools, BTW. I have no special experience here with WiX+patches+MSMs, but, it's as I said.
Last, but not least, you will have to choose, if you really want to keep this complexity in the future. As I remember, there are other possibilities in WiX to modularize / encapsulate parts of your software.
You can check the versions of files in merge modules and MSI files by opening them with Orca and looking in the File table. Or open the MSI file with Orca and then Transform=>View patch to see changes.
It may be obvious, but a binary versioned file will be replaced by a file with a higher file version. I mention because there is a belief out there that somehow "new" files replace "old" files, and that's wrong. Versions matter.
Generally you need to install a patch with an msiexec command that specifies REINSTALL=ALL REINSTALLMODE=omus. Double-clicking an MSP file will not necessarily just work unless you've arranged for it to do this internally with a custom action that sets them when PATCH is set.
The patch will not work if you break component rules. A common mistake is to remove a component during a patch, and that will result in an "advertised" update that doesn't actually update anything. In a verbose log look for SELMGR entries and text about removal of components is not supported. Setting the MSIENFORCEUPGRADECOMPONENTRULES property to 1 will fail the patch if you've done this.
If a file has no version whether it's overwritten depends on the replacement rules here, and there's some difference if the file is hashed or not:
https://msdn.microsoft.com/en-us/library/aa370531(v=vs.85).aspx
Also: how do you know the patch isn't working? If you have no file versions then you can't know if a file has been replaced unless you look very carefully. You cannot trust the dates because Windows changes timestamps when a file is installed. You really need to build binary files with file versions because everything like patches, hotfixes, service packs etc will use them to replace binary files. Otherwise for data files use file hashing.
I see several potential problems here, maybe even in addition to the other answers:
when you heat up files for your merge modules -gg autogenerates new component guids. This will not work with patches, since it'll basically add a bunch of new components (new guids each time!!). Also, you'll remove components this way, which is something you shouldn't do and which cannot be done easily, unless you still include the original merge module. And then you'll end up with path problems.
The tutorial for wix patching uses wixpdb files for diffing the original and the updated installer. With wixpdb files, merge modules will not be patched, irrespective of whether files changed in them or not. You will need to do administrative installations and then diff on the msi itself. You'll still have problem #1.
your wxs snippet is bad. At least the xml element is never correctly closed. Your Feature also has a MergeRef somewhere?
Some tips:
you can view what your patches do with a program called Orca. Open the original msi, then just drag your msp patch file on top of it.
rather don't use merge modules, they complicate things. You can also use heat to generate a fragment which you then simply include into your wix project.
use the wix patching approach (Patch element, not the PatchCreation element). It's easier, but you have the same control
don't autogenerate guids if you plan to update those autogenerated components with a patch. It won't be a problem with major upgrades :)
Just one important issue of a number of potential reasons while files are not updated correctly: You write, in your .msm is a high number of unversioned files, like .xml, etc.
Important rule:
EVERY unversioned file which is changed on the PC AFTER the first MSI install not by the MSI engine itself (e.g. you edited a config.xml file or so), will be normally NEVER updated by MSI again, not by patch and not by Major Upgrade. (With normally I mean, you have to take special actions, like uninstalling or especially specifying those files as socalled companion files).
I have a WiX installer which needs to install new bits for Interop.FOOBARLib.DLL to the GAC. The problem is that the version number is the same as the old version and the new bits do not get written the GAC on an upgrade. We execute the RemoveExistingProducts action after the InstallFinalize action.
We cannot move the RemoveExistingProducts action to earlier in the install.
The foobar.dll component is not my component so I cannot increment the type library version (which would cause the version of the interop to increment and all these problems go away).
Is there a way to FORCE the file to be upgraded in the GAC even if the version is the same? I want behavior similar to “gacutil.exe /f”.
The component looks like:
<Component Id="Interop.FOOBARLib.dll" Guid="{4E0C173E-34DF-4249-A3A6-5530047FA65B}" >
<File Id="Interop. FOOBARLib.dll" Name="Interop.FOOBARLib.dll" KeyPath="yes" Assembly=".net"/>
</Component>
What you're trying to do is called an In-Place update of an Assembly in the GAC. For this to work correctly both Interop.FOOBARLib.dll libraries must have the same assembly version, but the newer dll must have a higher file version. The file version attribute must be included in the new MSI's MsiAssemblyName table. Wix does not include this attribute by default, so you have to add the following parameter to your .wixproj file:
<SetMsiAssemblyNameFileVersion>True</SetMsiAssemblyNameFileVersion>
See also:
In-place updating using Wix
You can regenerate the interop assembly yourself and force it to get a higher version like this:
tlbimp /asmversion:1.2.3 /out:Interop.FOOBARLib.DLL foobar.dll
You could try to execute a custom action to delete the file, right before the components are installed. It's not recommended to use vbscript for custom actions but the example below should still illustrate the idea.
<CustomAction Id="ForceRemove" Script="vbscript" Execute="deferred">
<![CDATA[
Dim fso
Set fso = CreateObject("Scripting.FileSystemObject")
fso.DeleteFile("c:\somefile.dll")
]]>
</CustomAction>
<InstallExecuteSequence>
<Custom Action='ForceRemove' Before='InstallFiles'/>
</InstallExecuteSequence>
