|If the camera has a USB interface with most do then it will. The bus width has nothing to do with it.|
What you need to look at is that f the camera comes with an photo processing software that it will run under Windows 7. If it runs under Windows XP 32 bit then there is a very good chance it will also run under Windows 7 64 bit. Again the bus width has little to do with it. 32 bit software will run just as well in 64 bit windows.
