GlobalProtect Error During Installation: An instance of GlobalProtect is already present on the system.""
After un-installing the GlobalProtect client and trying to install a new client the following message appears:
"An instance of GlobalProtect is already present on the system. Uninstall the current version before attempting to install the new version of GlobalProtect"
- Remove the registry items within the following registry path (Windows OS):
HKEY_LOCAL_MACHINE\Software\Palo Alto Networks\GlobalProtect\PanGPS
- Run the following command as an administrator from the windows cmd line:
sc delete PanGPS
- Reboot the machine.
This will completely remove the GlobalProtect client from the machine and will allow users to install the new client without any issues.
