From WG WebSite,that's fine work.
The recommended method for uninstalling the MUVPN client is through the Control Panel Add/Remove programs icon. If, for some reason, this fails or a reinstallation fails, steps may be taken to uninstall parts of the client manually:
Caution: It is very important to deactivate the security policy before uninstalling the client (using the automatic uninstallation process or the manual uninstallation process). Failure to deactivate the policy can result in the PC crashing and the MUVPN client being unusable.
Caution: BACK UP YOUR REGISTRY. Failure to do so may result in an unusable Windows configuration. WatchGuard cannot be responsible for damage resulting from the (mis)use of this information. More information on backing up your registry can be found at the following Web address:
Remove the SafeNet VPN Adapter from the Network control panel.
Delete the following folders:
Program Files/Watchguard/Mobile User VPN/
Temp/
Delete the following files:
Windows/System/ire*.DLL
WinNT/System/ire*.DLL
Delete the following registry keys:
HKLM\Software\Zone Labs
HKLM\Software\WatchGuard
HKLM\Software\DeterministicNetworks
HKLM\Software\IRE
HKLM\Enum\Network\DNES (Windows 98)
HKLM\Enum\Network\DNEMAC (Windows 98)
HKLM\Enum\Network\DNEPRO (Windows 98)
HKLM\System\CurrentControlSet\Services\DNE (Windows NT/2000)
HKLM\System\CurrentControlSet\Services\DniVap (Windows NT/2000)
HKLM\.wgx (Windows 2000)
HKEY_CLASSES_ROOT\wgx_auto_file (Windows 2000)
Browse to: HKLM\Software\Microsoft\Windows\CurrentVersion\Uninstall\key
Scroll through every alphanumeric key and look for "Mobile User VPN" in every value. Delete the keys that contain "Mobile User VPN" - it may appear near the end, so make sure you look at the entire length of each value.
Reinstall the client with the automatic installer.
Uninstall the client from the Add/Remove Programs menu in the Control Panel.
