16 years agoThe driver in 9.1 does look to be signed properly, although I have not actually tried to install it yet.
I know the driver from Quartus II 7.2 SP2 works with Vista x64. This is what I have been using even with newer versions of Quartus. The drivers included with Quartus II 8.0 through 9.0 definitely do not work with Vista x64.
