Disallow multiple instances of installer

[srowe]

Is there some method by which only one instance of a specific installer can be run at any one time? Currently, I can launch our installer/uninstaller and then launch another. I'd like the 2nd instance to detect that the first one is running and just quit.

Hi

You may use the Terminate Program command to try and close a running instance. You may also use the Call DLL Function plug-in and invoke the FindWindowA API in user32.dll to find out if your target setup is running.

Hope that helps!
