SonicWALL Global VPN Client is a program which creates VPN (Virtual Private Networks).
You should install the current version, reboot and then. But when i try to reinstall the application error is coming 'Global VPN client is already installed, but the installed version number could not be determined. I have recently uninstalled Sonicwall Global VPN Client application(in regedit too).
