Is Vizard compatible with Vista 64-bit?
 

I am planning to purchase a new computer to be used with Vizard.
Is there any reason not to choose Vista Home Premium 64-bit OS?

Yes, Vizard will run on Windows Vista/7 64-bit. Keep in mind that Vizard is still a 32-bit application, so it won't be able to take advantage of 64-bit hardware (i.e. use more than 4 GB of memory). Also, if you are using any hardware devices with Vizard you will need to use the 64-bit version of the device drivers.

Works just fine on 64 bit vista. I run it all the time.
