Clavister SSL-VPN Client for Windows
My SSL-VPN Client does not work and Windows then complains about not being able to verify the signature for the SSL-VPN TAP driver.
How can I get the SSL-VPN client to work?
After the Windows 10 anniversary update, aka version 1607, Driver signatures were enforced. This caused the previous driver that was used for the SSL-VPN to fail. For that we released a new SSL-VPN Client, version 220.127.116.11, which contains a signed driver that works with the newer Windows versions.
If you have installed an older version of the SSL-VPN you must make sure to manually remove the old driver before uninstalling the SSL-VPN client in order for the new SSL-VPN client version 18.104.22.168 to have the correct driver installed.
You can remove the driver manually with the following steps:
After you have uninstalled the TAP Driver, proceed by uninstalling the currently installed SSL-VPN client and then install the SSL-VPN Client version 22.214.171.124 and it should work as intended.
The SSL-VPN client needs a signed driver in order to work on newer Windows machines. Clavister SSL-VPN Clients 126.96.36.199 and up contain a signed driver that works on new Windows machines.
If you have installed an old version of the SSL-VPN client previously you must manually remove the driver, then uninstall the client and install the latest SSL-VPN Client instead.
1. Remove the old driver
2. Uninstall the SSL client
3. Install SSL client version 188.8.131.52
