256MB ATI RADEON X600 HYPERMEMORY GRAPHIC CARD drivers.

Dear Forum Readers, I reformatted my computer today and I am having trouble installing the driver for my 256MB ATI RADEON X600 HYPERMEMORY GRAPHIC CARD. I downloaded the file I was supposed to download (called R119714) over at the Dell Technical support --> Drivers and Downloads Search Criteria. But, every time I try to run the file, a couple of seconds after the extracting has been completed, I get an error: "Setup was unable to complete the installation. Try to setup your display adapter with a standard VGA driver before running the setup." I am pretty sure I installed all the other drivers, I just can't get this one to work... Any help is appreciated, thank you in advance.
