Closing an existing application from NSIS befor installation starts.

Hi,

It would be great if someone can answer the below question.

How can I identify if the application(MyApp.exe) is running and if it is running I would like to close it before my installation begins.

Thanks for reading the question.

to kill the application:
ExecWait `taskkill /im MyApp.exe`

thats probably not the best solution, taskkill does not exist on all systems. You are probably better off checking for a mutex or window class and tell the user to close down your app

I agree but ... do you know how to do this ?

In its most basic form...



_retry:

FindWindow $0 "Class or Titlebar text"

IntCmp $0 0 _done

  MessageBox MB_OK "Please close [application]"

  goto _retry

_done:
