I am trying to check for .net Version with Wix 3.11 via Condition. This works fine until 4.5 like this:
<PropertyRef Id="NETFRAMEWORK45" />
<Condition Message="This application requires .NET Framework 4.5. Please install the .NET Framework then run this installer again.">
<![CDATA[Installed OR NETFRAMEWORK45]]>
</Condition>
Checking for anything above 4.5 seems not to be possible - at least not with this mechanism. How can I do that?
That method (PropertyRef) is syntactical sugar. The NetFxExtension preprocessor injects the implementation at compile time. WiX is currently lagging behind. The implementation you are looking for would be something like:
<PropertyRef Id="NETFRAMEWORK45" />
<Condition Message="This application requires .NET Framework 4.7.1. Please install the .NET Framework then run this installer again."><![CDATA[Installed OR NETFRAMEWORK45>=#461308]]>
</Condition>
https://github.com/wixtoolset/issues/issues/5575
Update (hot33331): Added a # before the number 461308. Without that it did not work for me.

I currently using the following markup in my WiX installer project to check if .NET Framework 3.5 or greater is installed.
there is no Release Reg_DWORD for .Net Framework 3.5 But you can detect it using the following RegistrySearch:
<Property Id="NET35INSTALLED" Secure="yes" Admin="yes"/>
<util:RegistrySearch
Id="Net35Installed"
Variable="NET35INSTALLED"
Root="HKLM"
Key="Software\Microsoft\NET Framework Setup\NDP\v3.5"
Value="Install"
Win64="no"
Format="compatible"
/>
To use it in a condition use NET35INSTALLED = 1.
See more information in the official documentation.
Visit :
https://www.mking.net/blog/detecting-dotnet-framework-versions-with-wix
there you see the check for 4.7.2 installed :
<PropertyRef Id='WIXNETFX4RELEASEINSTALLED'/>
<Condition Message='This setup requires the .NET Framework 4.7.2 (or greater) to be installed.'>
<![CDATA[Installed OR (WIXNETFX4RELEASEINSTALLED >= "#461808")]]>
</Condition>
You only need to replace the release key with the 3.5 version..
In my WiX installer, I do not want .NET installed automatically if it isn't installed. It should just give a warning or merely error out.
The reason to avoid it is explained here:
One HUGE word of
caution here: Because the .Net installer will technically be part of
your install chain, if the user installs .Net but then cancels your
install, your installer will still be listed in the Add/Remove
programs since one if it’s components (the .Net installer) completed.
Tread with caution.
He seems to be intentionally including it. But I'm not and I happened to set <supportedRuntime version="v4.5" /> which I guess isn't a real version (4.5 => 4.0 as far as this is concerned?). My WiX managed bootstrapper application exe automatically prompted me to download and install the "missing" .NET Framework.
For computers that ARE missing 4.0, I don't want this to happen. WiX also complains if I leave out:
<WixVariable Id="WixMbaPrereqLicenseUrl" Value="..." />
<WixVariable Id="WixMbaPrereqPackageId" Value="..." />
in which I literally leave in ... because I don't want it to work anyway.
In this thread, #Shruthi asks
Is there a way to replace the prerequisite .Net install UI with just an notification to the user that they need to install a particular version of .Net before they can install the bundle?
And Rob Mensching replies:
Yes, that is possible now.
... BUT HE DOESN'T ELABORATE. How is it possible now?
Thanks!
===============
In my Bundle's Bootstrap.Config:
<startup useLegacyV2RuntimeActivationPolicy="true">
<supportedRuntime version="v6" /> <!-- Pretending it's the future! -->
</startup>
The Bundle itself does not reference any .NET stuff and does not reference WixNetFxExtension and uses the custom <BootstrapperApplicationRef Id="ManagedBootstrapperApplicationHost" />
To answer how to handle checking for the .Net 4.0 Framework include the WixNetfxExtension in your project
then under product add a reference to the property NETFRAMEWORK40FULL and put a condition on it.
<PropertyRef Id="NETFRAMEWORK40FULL"/>
<Condition Message="This application requires .NET Framework 4.0. Please install the .NET Framework then run this installer again.">
<![CDATA[Installed OR NETFRAMEWORK40FULL]]>
</Condition>
for the chained case again include wixnetfxextension and include NetFx40Redist package group
<PackageGroupRef Id="NetFx40Redist"/>
I'd like to validate both .NET framework 4.0 and 4.5 should be installed at server before proceeding a installation. Hence I used the following snippet, but I don't know about 4.5 validattion, which was not listed in the link Reference
<PropertyRef Id="NETFRAMEWORK40FULL"/>
<Condition Message='This setup requires Microsoft .NET Framework 4.0 Full package or greater needs to be installed for this installation to continue.'>
<![CDATA[Installed OR NETFRAMEWORK40FULL]]>
</Condition>
The NETFRAMEWORK45 property can be used the same as the NETFRAMEWORK40FULL. Note there is no "client" or "full" framework for The .NET Framework v4.5. There is just one. So the following code should do what you want:
<PropertyRef Id="NETFRAMEWORK40FULL"/>
<PropertyRef Id="NETFRAMEWORK45"/>
<Condition Message='This setup requires Microsoft .NET Framework 4.0 Full package or greater needs to be installed for this installation to continue.'>
<![CDATA[Installed OR NETFRAMEWORK40FULL]]>
</Condition>
<Condition Message='This setup requires Microsoft .NET Framework 4.5 package or greater needs to be installed for this installation to continue.'>
<![CDATA[Installed OR NETFRAMEWORK45]]>
</Condition>
Note that .NET Framework v4.5 is an in place upgrade of .NET Framework 4.0 so checking for both could get you into a situation where you'll never satisfy both conditions. You might want to just check that .NET Framework v4.0 or .NET Framework v4.5 is installed. That condition would look more like:
<Condition Message='This setup requires Microsoft .NET Framework 4.0 Full or 4.5 package or greater needs to be installed for this installation to continue.'>
<![CDATA[Installed OR NETFRAMEWORK40FULL OR NETFRAMEWORK45]]>
</Condition>
When installing an application that can use either .NET 4.0 or 4.5, what is the best practice when installing the prerequisites .NET framework? And how do you implement it using Burn in WiX?
These are the options and trade-offs that I am aware of:
Option 1: Install .NET 4.0 (just what you need)
Advantages: None known (except for Windows XP, where this is the only choice)
Option 2: Install .NET 4.5 if .NET 4.5 is not present
Advantages: User won't have to install .NET 4.5 later for future
apps. App won't experience a .NET version change when user later does
upgrade to .NET 4.5. App immediately gets performance improvements of
.NET 4.5.
Option 3: Install .NET 4.5 only if neither .NET 4.x is present
Advantages: Much faster deployment than option 2 if .NET 4.0 is
already installed. If it's not, then the advantages of option 2
apply.
As far as I can tell, the best practice would be option 2 if the performance improvements are important and option 3 if average deployment speed is important. Does this sound right? Am I missing any advantage to option 1? Most importantly, if option 3 does make sense, how do you implement it using Burn when installing .NET from the web?
Below is how I detect .NET in my bundle. Note the use of DetectConditions and InstallConditions. The DetectCondition will check whether or not the specific package is installed, whereas the InstallCondition can be used to override the DetectCondition to specify when the package should be installed. For example, on XP you can't install .NET 4.5 so my InstallCondition prevents installation in such a case.
<util:RegistrySearch Root="HKLM" Key="SOFTWARE\Microsoft\Net Framework Setup\NDP\v4\Full" Value="Version" Variable="Netfx4FullVersion" />
<util:RegistrySearch Root="HKLM" Key="SOFTWARE\Microsoft\Net Framework Setup\NDP\v4\Full" Value="Version" Variable="Netfx4x64FullVersion" Win64="yes" />
<!-- .NET 4.5 only installed if Vista or higher AND it's not already installed-->
<PackageGroup Id="Netfx45">
<ExePackage Id="Netfx45" Cache="no" Compressed="yes" PerMachine="yes" Permanent="yes" Vital="yes" InstallCommand="/q"
SourceFile="C:\Program Files\Microsoft SDKs\Windows\v7.0A\Bootstrapper\Packages\DotNetFX45Full\dotnetfx45_full_x86_x64.exe"
DetectCondition="(Netfx4FullVersion="4.5.50709") AND (NOT VersionNT64 OR (Netfx4x64FullVersion="4.5.50709"))"
InstallCondition="(VersionNT >= v6.0 OR VersionNT64 >= v6.0) AND (NOT (Netfx4FullVersion="4.5.50709" OR Netfx4x64FullVersion="4.5.50709"))"/>
</PackageGroup>
<!-- .NET 4.0 only installed if XP AND it's not already installed -->
<PackageGroup Id="Netfx4Full">
<ExePackage Id="Netfx4Full" Cache="no" Compressed="yes" PerMachine="yes" Permanent="yes" Vital="yes" InstallCommand="/q"
SourceFile="C:\Program Files\Microsoft SDKs\Windows\v7.0A\Bootstrapper\Packages\DotNetFX40\dotNetFx40_Full_x86_x64.exe"
DetectCondition="Netfx4FullVersion AND (NOT VersionNT64 OR Netfx4x64FullVersion)"
InstallCondition="(VersionNT < v6.0 OR VersionNT64 < v6.0) AND (NOT (Netfx4FullVersion OR Netfx4x64FullVersion))"/>
</PackageGroup>
Then if you want to install one of the packages, just reference it in your chain:
<Chain>
<PackageGroupRef Id='Netfx45'/>
</Chain>
With regards to your specific question, I would install whatever framework version the application was tested against. If tested against both .NET 4.0 and .NET 4.5 I suppose it is a judgement call, however I would try to simplify the setup experience as much as possible. So if .NET 4.0 were already installed and the application does not require .NET 4.5, I would not install it.
Also, there is a disadvantage to Option 2 if you are using a custom Managed Bootstrapper Application. Let's say you have .NET 4.0 installed and your managed bootstrapper requires .NET 4.0 (or greater). When you run the installer it will install .NET 4.5 which replaces .NET 4.0, forcing your installer to reboot halfway through because it was using .NET framework at the same time it was being updated. Again, this is only an issue if you are using your own custom managed bootstrapper.
I am trying to detect .net framework 2.0 service pack 2. But it seems that wix is unable to detect that.
below is the script that i am using.
NAnt:
<exec program="${wix.dir}\light.exe" workingdir=".\wix" commandline="-ext WixUIExtension -ext WixNetFxExtension -cultures:en-us SampleFirst.wixobj -out ${release.dir}\NantTest.msi"/>
wix:
<PropertyRef Id="NETFRAMEWORK20"/>
<Condition Message="This application requires .NET Framework 3.5 SP1. Please install the .NET Framework then run this installer again.">
<![CDATA[Installed OR (NETFRAMEWORK20_SP_LEVEL and NOT NETFRAMEWORK20_SP_LEVEL = "#2")]]>
</Condition>
It is able to detect the ,net framework. But it is not detecting service packs. Any suggestion?
Just use
<PropertyRef Id="NETFRAMEWORK20_SP_LEVEL"/>
instead of
<PropertyRef Id="NETFRAMEWORK20"/>
