I am trying to install the latest driver pack that Tascam has for the US-1641 on a 64-bit windows 7 OS, but every time I try to install it the computer restarts in the middle of the process. It then boots up and asks if I want to boot in safe mode, so I have a feeling it is something in the system. I have checked for updates to the OS, but it keeps saying it is up to date. I have tried running it in compatability mode, and had the same results. i have tried running it as an administrator and still the same thing happened. Any one have any idea what I should do?
