-BlockExecution Turn off the popup?

I’m using the line:

Show-InstallationWelcome -CloseApps 'iexplore,helppane' -CheckDiskSpace -PersistPrompt -BlockExecution

because I have a vendor MSI that insists on launching their website as well as a helpfile program after installation is complete, even with ‘/qn ISSILENTINSTALL=1’ parameters.
The blocking is working well, but I don’t want the popup “Launching this application has been temporarily blocked…”

Is there a way to turn off the -BlockExecution popup?

you MIGHT be able but you will have to modify AppDeployToolkitMain.ps1

Near the bottom look for this code:

	#  Attempt to acquire an exclusive lock on the mutex, attempt will fail after 1 millisecond if unable to acquire exclusive lock
	If ((Test-IsMutexAvailable -MutexName $showBlockedAppDialogMutexName -MutexWaitTimeInMilliseconds 1) -and ($showBlockedAppDialogMutex.WaitOne(1))) {
		[boolean]$showBlockedAppDialogMutexLocked = $true
		Show-InstallationPrompt -Title $installTitle -Message $configBlockExecutionMessage -Icon 'Warning' -ButtonRightText 'OK'
		Exit 0

comment out the line starting with Show-InstallationPrompt

Good luck.

That worked!
Thank you. You saved me a lot of time searching for that one line (12063).
