I have did some investigation into drivers for WIndows 7 64bit.
From what I have read, Win7 64bit will refuse to load any driver that is not certified.
What truth is there in this?
Also, is it hard to make a driver certified?
I am only asking because this possibly could cause problems with the recently made 64bit drivers for the USB version of SIO2PC.
Windows 7 does have a 'pay to play' driver system, it will not load any drivers that are not signed with a commercial signing certificate.
All of the drivers I provide are fully signed and can be loaded in 32-bit and 64-bit editions of Windows. You just have to use the appropriate driver for the appropriate OS. 32-bit windows will only load the 32-bit drivers, 64-bit windows likewise requires the 64-bit versions of the drivers.
