Win7 64-bit BSOD

[Trelligan]

Initial installation (.msi file) hung after about 2/3 on the progress bar; permission dialog had already been answered twice.
Reboot, and seemed to install fine and quickly. Tried to start service, and got a Blue Screen of Death (BSOD). There wasn't much time to read it, but there was something at the top about the driver being "not less than or equal to" something.

I applaud the effort, but wish my system was compatible.

I tried to install tcpcrypt yesterday night and got exactly the same behaviour.
Additionally, I tried again to launch tcpcrypt that I found in program files and after a second of displaying the gui it BSOD again (which is really worrysome for something that shouldn't impact hardware or drivers?).
