We have a PowerShell snapin that requires version 3.0 of PowerShell to function. So we used the following file element in a WiX (3.8) file:
<File Id="MySnapin.dll"
Name="MySnapin.dll"
Assembly=".net"
KeyPath="yes"
Vital="no"
Checksum="yes"
DiskId="1"
Source="$(var.FilesPath)\Bin\MySnapin.dll"
AssemblyApplication="MySnapin.dll">
<ps:SnapIn Id="MySnapin"
Description="This is a PowerShell snap-in"
Vendor="My Company Inc."
RequiredPowerShellVersion="3.0">
<ps:FormatsFile FileId="MySnapin.format.ps1xml" />
</ps:SnapIn>
</File>
However, when installing this the snapin cannot be found in powershell (Get-PSSnapIn -Registered). When examining the registry it turns out that the snapin has been registered in HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\PowerShell\3\PowerShellSnapIns\MySnapin. But when running installutil.exe on the DLL, the registration ends up in HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Microsoft\PowerShell\1\PowerShellSnapIns\MySnapin, and powershell finds it properly. It seems this a bug in WiX Toolset?
