Sonicwall VPN Client and Globesoft Multinetwrok Manager

Hello,
i have installed the Windows Vista Beta 2 and want to test it with the VPN
Client from Sonicwall. The virtual adapter was installed or not - i dont
know. The installation ends without any errors but i cant see the adapter
under the network environment or the device manager. When i will start the
program, i become an error message and the program ends without an completed
start.
I dont know where the error is. I hope anyone have an idea.
Also the installation of Multi Network Manager was not completed. I must
test this program under Windows Vista and at the moment i'm not affraid to
use it. I hope the final version can work with Sonicwall and MNM from
Globesoft.
Best regards for your answer, Mario
