Error in use check process

Nobody want to write a DLL module for check process ?
The CheckProcess not work on my Windows XP Pro. I have an error message 0xc0000135 in command line mode !

I just want to chek if my application is running when i start my installer (newer version 😉).
If my application is running i want to said (messagebox) 'please close your application before start the installer'.

If you write an NSIS script who make that, i'm very happy to use it 😁

you can find such an example in the archive
