I did go to google.com before I asked the question on this forum. However, I apologize and should have been more specific on my question. I have never downloaded the B3D projector. Yet, it is own my PC. I have only installed 3 software programs: Windows XPpro, Office 2000 premium, and the usual critical updates for XPpro. I don't know how critical the B3D projector is in relation to my PC. I guess I'll just leave it there. Well, thanks for your help anyway.
