Bison web cam driver 6.32.0.7

I have two notebooks (MSI VR610X) they both work with WinXp SP2, it is said that the driver works for XP. I installed it, but it doesn’t work =)… it is supposed to make some bubble down by the clock saying “web cam ready or something like that” but it doesn’t show any signs of doing anything if you can advise me what to do I’ll be very thankful =).

Regards.
