Recently we got a new 64-bit system running Vista 64-bit. I tried installing Revit 2009 64-bit and got plenty of errors when trying to run the program.
As such I'm a bit wary of installing the 64-bit version of 2010 on there, although I'm guessing it will work better since it was originally designed to be a 64-bit program. When I clicked to install 2010, however, the only option it gave me was the 64-bit version. Is this how it's supposed to work?
