Make your application set a mutex and use the System plug-in in the installer to check whether the mutex exists.

Show, please, piece of the script-code demonstrating this possibility.

Try it this way

  GoTo Running
    
  Exit:
    MessageBox MB_YESNO|MB_ICONEXCLAMATION "$(MUI_TEXT_ABORTWARNING)" \
      IDNO Running
    Quit

  Running:
    FindWindow $R9 "Becky2MainFrame" ""
    IntCmp $R9 0 NotRunning
    MessageBox MB_OKCANCEL|MB_ICONEXCLAMATION "Becky! Internet Mail \
      is akticv.Pls close Becky." IDCANCEL Exit
    GoTo Running
  NotRunning:

To determine the right window (eg "Becky2MainFrame") uses this lite program:

You need the label "Win Class" - NSIS can also perfom on special sub windows here called "Win Title".
Pls read the manual to this.

Using a mutex is still a better way than finding windows. Check MSDN for the CreateMutex API.

It is obviously even for hedgehog ;) But how I can use WinAPI functions in NSIS-script I haven't found in docs :(

Check out ${NSISDIR}\Contrib\System and examples, with this plugin you can call any API from windows

good luck,
Ramon

This thread talks about using a mutex with NSIS.
