Bridge doesn't recognize processor

Hello,
I'm using Bridge CS3 2.1.1.9 under MS Vista Home Premium, Processor is a Intel Dual Core E8200.

After starting Bridge, I get the message (copied from a different thread):
Adobe Bridge
This application requires an Intel Pentium 4, Intel Celeron, Intel Core Duo or Intel Core 2 compatible processor. (0/6/5894)
This application may perform poorly. Are you sure you want to continue?

Thank you for your help

Jürgen
