I'm afraid I don't quite understand what the problem is, but if you are trying to delete/uninstall jv16 PowerTools 2005 and it fails, please use the Windows Task Manager to ensure jv16pt.exe is not running. If it is, you should kill it and then try to uninstall/delete the program.
If that doesn't work, you should be able to uninstall the program in any case using the Windows Safe Mode.
