Uninstall fails because program is running. How do I make Inno Setup check for running process prior to attempting delete?

Question

Inno Setup fails to remove components during uninstall cause my program is still running and the executable cannot be deleted. How do I have it check to see if it is running

Answer 1

We used an other way than described above. Because this is an uninstallation we can kill the application and unistall it. The simpliest way, when u can't use AppMutex: (related to Really killing a process in Windows)

[UninstallRun]
Filename: "{cmd}"; Parameters: "/C ""taskkill /im .exe /f /t"

Hope somebody will help this. I searched a long time for this.
