Arduino software shuts down immediately

Hi,

I have Arduino UNO model SMD R2 and an AMD 64 bit PC.
I downloaded windows instalator and the software installed fine. Upon connecting the board a message popped up saying that the driver installed fine. The problem is that the software shuts down immediately after I start it up and its process dissapears from task manager. Does anyone have any idea how to make it work? Thanks

Try using the Windows Zip file for non-admin install instead
