PowerShell script to ensure only one instance of MEP is running

[Cory]

I had a problem with a server where multiple administrators would try to log in resulting in multiple instance of MEP crashing into each other to do administrative tasks. I started to write a start-up macro that would conditionally abort launch if an instance was already running but MEP cannot 'see' processes running under other users. Since PowerShell can see processes for all users I wrote this little script that will launch MEP only if it's not already running regardless of user. Thought I'd post it here in case anyone might benefit from it.

if (-Not (Get-Process "MacExp" -ErrorAction SilentlyContinue | Where-Object {-not $_.HasExited }))
{
  & "C:\Program Files (x86)\Macro Express Pro\MacExp.exe"
}
