Something weird happens in Vista, where I adjust any of the networking properties, then I have to do a System Restore to a state before the software was installed, and then re-install SoftEther. Fortuntely, installation and configuration are straightforward, which allows me to get the VPN back up and running in just a few minutes if I had to restore and reinstall.

Hi there. I have the same problem on win 8 64bits. I need the vpn to play PSO 2.
I tried installing the soft whit administrator permissions and have the same result.
If someone have the solution i'll be very very grateful!
Thanks in advance.

To make the problem clear, try on the clean-installed Windows XP SP3 (e.g. use another HDD as the boot-disk temporary).
