Today I'm re-installing Win 7 64bit Professional. During this process I will be re-installing all of my drivers of course. Now it has been over 2 years since I've done this and I have forgotten about how to install my HOTAS Cougar.

What drivers/software do I need for my operating system?

Any help advise would be greatly appreciated to make this installation as pain free as possible.

Thanks.

You just use the 64-bit Vista driver package, with the installer set to Vista compatibility mode (this part is important, otherwise it won't install properly). Works fine after that.
