Wix Toolset execution of Powershell-script does not work - powershell

Question

I want to run a PowerShell-Script before and after the installation with the msi-file. Below you can see the basic content of my configuration in Visual Studio 2013 for wix-project. The msi is compiled without errors and I can run the msi-file and go through the steps till the end of installation without errors.
In the log I can see, that the CustomAction had been started, but this cannot be true because the directory that should have been created by the underlying script has not been created.
If I run the script-file manually by powershell everything runs well. So the script itself should work and does not throw an error.
Any suggestions what is wrong here?

Answer 1

I'm not sure if the CustomActioncan find the PS1 file under the local directory. Try to adapt the WIX file with following blocks
<!-- Ensure PowerShell is installed and obtain the PowerShell executable location -->
<Property Id="POWERSHELLEXE" Secure="yes">
<RegistrySearch Id="POWERSHELLEXE"
Type="raw"
Root="HKLM"
Key="SOFTWARE\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell"
Name="Path" />
</Property>
<Condition Message="This application requires Windows PowerShell.">
<![CDATA[Installed OR POWERSHELLEXE]]>
</Condition>
....
<CustomAction Id="RegisterPowershellCommandStop"
Property="CallPowerShellCommandStop"
Value=""[POWERSHELLEXE]" -NoLogo -NonInteractive -InputFormat None -ExecutionPolicy Bypass -NoProfile -File "[INSTALLFOLDER]ServiceStartStop.ps1" "[SERVICENAME]" "stop""
Execute="immediate" />
....
<DirectoryRef Id="INSTALLFOLDER">
<Component Id="CMP_StartStopServicesScript" Guid="*">
<File Id="FILE_StartStopServicesScript" Source="!(wix.binDirectory)\ServiceStartStop.ps1" KeyPath ="yes" />
</Component>
...
In this case we're calling PS ("stored" in [POWERSHELLEXE]to start ServiceStartStop.ps1 (located under [INSTALLDIR]).
Hope that helps.
