[wix-users] EXT: Install .Net 4.8 if it's not installed as a condition

Tue May 5 08:54:57 PDT 2020

I have my custom UI bootstrapper set to use .NET 4.8 and that seems to trigger it nicely.  I also have a Wix shared library with the code to install 4.8.  We have a requirement to install without Internet, so the command is set up that way.  It would be different if you needed it to download from the Internet.

The NetFx48.wxs that I use is below.

I set the variable to point to my prerequisites folder:
    <WixVariable Id="NetFx48RedistPackageDirectory" Value="Prerequisites\" />

And then have the package group ref:
      <PackageGroupRef Id="NetFx48Redist" />

Hope that helps.

Subject: EXT: [wix-users] Install .Net 4.8 if it's not installed as a condition

Hi,

I know how to check whether .Net 4.8 is installed as pre-existing condition. However, I want to install it if that's not installed yet. Has anyone gone through this path and can advise me? I'm fine to handle that either at bundle level or in the MSI package itself.

I could see it's quite easy for .Net 4.5 at bundle level in bootstrapper ( https://wixtoolset.org/documentation/manual/v3/howtos/redistributables_and_install_checks/install_dotnet.html
):

<Chain>
    <PackageGroupRef Id="NetFx45Web"/>
    <MsiPackage Id="MyApplication"
SourceFile="$(var.MyApplicationSetup.TargetPath)"/>
</Chain>

However, up to .Net 4.6.2 the package group IDs exist ( https://wixtoolset.org/documentation/manual/v3/customactions/wixnetfxextension.html).
There is no simple way for 4.8. I found a harder approach for 4.7.2, but couldn't apply to my scenario for 4.8.

Any support is much appreciated.

Thanks,
Tigran
