Thank you for your response.
We only build a 64-bit version of our installer.
Here’s my registry component:
<Component Id="RegVersionInfo" Guid="*" Permanent="no">
<RegistryKey Root="HKLM" Key="SOFTWARE\Company\Product">
<RegistryValue Action="write" KeyPath="yes" Name="Location" Type="string" Value="[INSTALLFOLDER]"/>
<RegistryValue Action="write" Name="Version" Type="string" Value="[PRODUCT_MAJOR_VERSION].[PRODUCT_MINOR_VERSION].[PRODUCT_UPDATE_VERSION]"/>
A file named Test.ps1 is delivered by the installer on disk.
I have the following custom actions to then call Test.ps1:
<CustomAction Id="CallTestPowerShell_cmd" Property=" CallTestPowerShell" Execute="immediate" Value='"Powershell.exe" -NonInteractive -WindowStyle Hidden -NoProfile -ExecutionPolicy Bypass -NoLogo -InputFormat None -File "C:\Scripts\Test.ps1" ' />
<CustomAction Id="CallTestPowerShell" BinaryKey="WixCA" DllEntry="CAQuietExec" Execute="deferred" Return="check" Impersonate="yes" />
Scheduled as so:
<Custom Action="CallTestPowerShell_cmd" After="CostFinalize" />
<Custom Action="CallTestPowerShell" Before="InstallFinalize" >(NOT Installed AND NOT REMOVE) OR (MAINT_BUTTON_PRESSED = 2)</Custom>
Test.ps1 is failing on the following command:
Set-ItemProperty -Path “HKLM:\SOFTWARE\Company\Product” -Name “Name” -Value “Value” -ErrorAction Stop
And the error that I get is that the path for Set-ItemProperty does not exist.
Hope that helps a bit?

Perhaps there's a bitness mismatch between what you expect and reality?
How are you locating powershell.exe?
Actually, can you show us all your authoring related to this powershell script? How is it installed? How is it run?

I am hoping someone can help me understand why my custom action is having difficulties writing to the registry. I KNOW there are built in tools to write registry entries, however, we have a PowerShell script file that is delivered by the installer, and we then run this as a custom action. The PowerShell script also has to run in other scenarios, so it really can't be integrated into the installer other than a custom action that runs the script directly.
The PowerShell script tries to write to the registry at HKLM:\Software\...
I know our installer creates the registry key appropriately because it was always working, but now this new script fails with an error indicating the key is invalid.
My custom action is deferred with impersonate set to no, and it is scheduled between InstallInitialize and InstallFinalize.
Also, related, we saw a similar issue with accessing files from these scripts that were down in C:\Windows\System32\.
Are these blocked locations or something? I've read about some virtual registry or something in older versions of Windows used by installers?
Thank you for your time!
