I created an MSI file that copies the picpick.exe to program files and add a registry value to the startup "run".
I've added it to Group Policy in my company to install it on all the computers.
On some computers everything works fine (on most). However on some others, it seems to install, and I see the picpick icon in the task bar, but "Print Screen" doesn't work (nor does all the other key combinations).

I know it's very difficult to detect that kind of problems, but if anyone know or just have a thought on how to help, please do, it will be greatly appreciated.
You would..
