SonicWALL VPN Client Removal Toolby Chris Hoffman
The SonicWALL VPN client is an application that connects to the virtual private networks running on SonicWALL network security devices. It installs a network driver that doesn't always uninstall properly, so SonicWALL provides an official VPN client removal tool.
The SonicWALL Global VPN Client, or GVC, includes a network driver known as the Deterministic NDIS Enhancer, or DNE, driver. This driver binds to the network adapter in Windows. The normal SonicWALL Global VPN Client uninstaller doesn't always uninstall the DNE driver properly.
If the DNE driver is still present, users trying to install a newer version of the SonicWALL VPN client on the computer encounter an error message. Users need to run the official clean-up tool before installing the new version if the error message appears.
Users can download the Global VPN Client Clean Up Tool from SonicWALL's support website. SonicWALL provides the "GVCUtil32.zip" file for 32-bit versions of WIndows and the "GVCUtil64.zip" file for 64-bit versions of Windows.
