Compatibility issue with ATI Graphics Card and its Driver

Hi,
I recently bought a laptop from Compaq. My laptop description is:
Processor Type: AMD Athlon™ Dual Core processor P360 2.3 GHz
Chipset : AMD Chipset Ati
RAM : 2Gb DDR3
Hard Disk : 500 GB HDD
Screen Size : 14" HD Led Display
Optical Drive : DVD R/W
Graphics Card : ATi Radeon HD 6370 with 512 MB DDR3 Dedicated
Audio/Speaker : Altec Lansing Speaker with 3D effect & full duplex
OS: : Windows 7 32 Bit
Now my problem is about my Graphics Card. I downloaded ATI Catalyst 11.6 32 Bit from ATI Site. But when I setup ATI Catalyst, it shows me that the driver doesn't recognize my Card. What may be the problem? Am I doing something wrong? Please let me know.
