I have installed the Windows 7, 64 bit beta version using the upgrade from Vista Home Premium 64 bit. After the update, when I tried to run Sonic Wall client it wanted to do an install. I have tried the standalone client installer for SonicWall, the Vista Beta. It wants 'dne64x.sys', which I have been unable to locate on the Windows 7 disk or on the net. That is as far as I have been able to get.
