Running remote GUI app in Powershell

powershell powershell-remoting

We have a custom comonent that wraps some of the functionality of powershell so it can be used frim BizTalk 2006. For most operations (checking a file path, copy or move a file) this works fine. However we have the need to fire up a GUI app remotely to do some processing. The component itself handles the connection to the remote box, all we have to do is set some parameters and then tell it to execute a command

Start-Process -FilePath "path to exe" -ArgumentList "arguments for exe" -WorkingDirectory "workingdir for exe"

The issue is this: If we run this from a powershell command line on the box itself, this works fine. However when we fire it up remotely (from BizTalk, from a test harness, even using a remote Powershell command line and connection via Start-PSSession), this app will run briefly then exit without actually doing anything. My suspicion is that because the exe in question requires a GUI to load to run the process, that it is this that is causing an issue. I've tried everything I can think of, including -NoNewWindow and -WindowStyle but to no avail. Any help getting this working would be very much appreciated.

Note: We do not have access to the source for the application we are trying to run as it is an older win32 application, and no batch or command line version of this application has been supplied.

Using standard PowerShell methods (WinRM, WMI) you can't launch applications with GUI. The only solution I know about is to use PsExec from SysInternals (or similar tools). It can launch applications which present GUI to the user. Your command line will look like this:

& ".\psexec" -accepteula -i "\\computername" -u "domain\username" -p "password" "command line"
  • -accepteula — silently accept EULA.
  • -i — allow GUI.

Other solutions are more hacky, including remote adding of tasks to the scheduler.
