I want to check to see if a vhdx is still mounted and unmount it if there’s an error in the install script. I thought I could just put code in the ‘Catch’ section at the end of the ‘Deploy-Applications.ps1’ script. Apparently not.
Is there anything I can do to make that work?

Test-VHD is probably your best bet https://technet.microsoft.com/en-us/library/hh848580.aspx
I suspect you need to add -ErrorAction ‘Stop’ to ensure you get a terminal error to get ‘Catch’ to work.

I’m not trying to test anything with the vhd, I’m just trying to get some code to run if the script crashes for some reason. I can figure out what to do with the vhd etc.
I think -ErrorAction ‘Stop’ is the default for the Deploy-Application.ps1 script anyway. It does error out when something catestrophic happens.
How do I add code to run when the script exits suddenly?

Then your original idea should work UNLESS the error happens before Resolve-Error is declared.
If that is the case, look at the code I proposed in issue 163

All I’m doing (I’m sorry, the vhdx was a bit of a red herring) is using
Execute-Processwith a non-existent executable to trigger the fail. Then I want to insert some code that runs when the fail happens.
I’d be happy if
Write-Host 'Something bad just happened'ran 😉 I can fill in the rest later.

I’m just placing something like
Execute-Process -Path 'C:\temp\something.exe'in the Installation section of the script. It’s not very important except that I’m forcing an error to occur, something.exe doesn’t exist.
Then I put some code in the Catch at the end of the script thinking that it would execute when the function failed.

I tried and got this:
