How to Prevent or Supress Unexpected Return or Exit Codes in Successfully Installed Applications?

Question

We have some Intel and HP application installation task sequences that are successful, but the end of the deployment there is always a yellow screen warning about unexpected return codes such as "14".
I think most of these are because the applications are looking for a interactive restart that is not done until the MDT task sequence does a reboot.  For instance, a task sequence that installs Intel AMT software and drivers pops up a dialog box asking
the user to click to restart now or restart later even though the command is run as "setup.exe -s."  Since no one clicks on this pop up and the machine reboots via the task sequence, it creates this unexpected return code. 
Are there additional command line switches that can be added to the task sequences to suppress the reboot prompts and make these applications exit gracefully without causing these warnings at the end of the deployment?

Answer 1

I usually create a powershell wrapper for applications that exit funny. An example would be -
#GET CURRENT DIR
$mydir = Split-Path -parent $MyInvocation.MyCommand.Path
#SET VARAIBLE TO PASS INSTALL COMMAND WITH SPACES
$command = @"
setup.exe /s
#MOVE TO INSTALL DIR
Set-Location C:\Install\Folder\
#RUN INSTALL
cmd.exe /c ""$command | out-null
#EXIT CLEANLY
exit 0
Save this script inside where your Application is located, and then create an application that runs the script inside of the Deployment Workbench.  The only problem with this is you need to be sure your install works, as you're basically just ignoring
any errors the application has.  Down at the bottom, you can see the exit being passed back to MDT to continue cleanly.  Good luck.
I don't understand how to do this sine I have never users Powershell in MDT.
Do I just edit the script changing C:\Install\Folder to the actual local path the application is stored on in the MDT server?
Do I just name it with a .PS1 extension and run it as a command line or as an application?
