I am having the exact same problem, Installing Lifecam worked fine on my laptop But I get the same "unexpected error" message you are getting on my desktop. Which pisses me off, I know I have plenty of disk space, I know I am well over the minimum requirements, So I guess I must be having an "unexpected error"... wow.. thanks.

So how about some real help? Any ideas what might be going on? or even Better any programs out there you guys recommend for a webcam? I REALLY love Apples PHOTOBOOTH, now thats one enjoyable little program. Too bad there's nothing like that for Windows.. or is there?
