Hello and Welcome to PCHF on this glorious day - the sun is shining, birds churping.....
Oh ya sorry back to the problem.
It kind of sounds like a permission problem, especially the last part.
The install s/w tells me that it cannot write to the registry and was unable to initialize the driver
Have you recently changed your login name?
I have never heard of that problem with Webshots, seems very weird that it has all of a sudden started.
Anyway have you tried running spyware software e.g. Microsoft Anti-Spyware

Also are you running any antivirus software?
