PowerShell v1.0 doesn't have a -file argument. It does have a -command argument
which I'm using. Through trial and error I've discovered that it also works by
omitting -command (on the command line at least).
I typically setup my command line as follows (without the line breaks and
additional spacing):
<commandLine>
"[POWERSHELLEXE]"
-Version 1.0
-NoProfile
-Command $ep = Get-ExecutionPolicy ;
Set-ExecutionPolicy RemoteSigned ;
C:\InstallDir\SampleScript.ps1 ;
Set-ExecutionPolicy $ep ;
exit $error.Count
</commandLine>
This requires admin privileges which the installer already requires. In any
case, my original example was a minimal example that could be used to reproduce
the behavior (given an appropriate execution policy setting).
Here's another contrasting example:
<!-- Action Style 1 -->
<CustomAction Id="SetPSCmd"
Property="PSCmd"
Value=""[POWERSHELLEXE]" [#SampleScriptPS1]"
Execute="immediate"
Return="check"/>
<CustomAction Id="PSCmd"
BinaryKey="WixCA"
DllEntry="CAQuietExec"
Execute="deferred"
Return="check"/>
<!-- Action Style 2 -->
<CustomAction Id="PSCA"
Property="POWERSHELLEXE"
ExeCommand="[#SampleScriptPS1]"
Execute="deferred"
Return="check"/>
<InstallExecuteSequence>
<!-- Action Style 1 -->
<Custom Action="SetPSCmd" Before="PSCmd"/>
<Custom Action="PSCmd" After="InstallFiles"/>
<!-- Action Style 2 -->
<Custom Action="PSCA" After="InstallFiles"/>
</InstallExecuteSequence>
Action style 1 is my original example which hangs. Action style 2 does the
exact same thing but it shows a console window while the powershell script
executes. I currently use action style 2 because it actually works. Action
style 1 should have the same effect but omit the console window but instead it
hangs. (In other words, I don't think the problem is with my command line as
I've confirmed it works multiple ways, including a different style of custom
action.)
