Here is a link to MSI and drivers for that card from MSI
http://us.msi.com/product/vga/N210-D512D2.html#/?div=Driver&os=Win7%2064
All you do is download the driver for the video card and install the driver.
After you do that, shut down the computer, install the video card, and re-start the computer.
The driver should be detected and installed for that video card and you should be good to go.
So, YES there is a 64 bit windows 7 driver available, directly from the card manufacturer.
A sweet deal on a video card that will solve your problem!
the best,
