AutoCAD fatal error after Ccleaner

I think I may have found a working fix for this a few months back, but didn't save it. It seems that whenever we run maintenance on some of my Engineers' laptops, after running we get fatal errors in AutoCAD. I'm asking if anyone has seen this before, because I believe we found the solution having to do with running Ccleaner. I run a repair install on the affected machines, and then AuoCAD is ok again until the next time I run Ccleaner. I'm thinking that if I exclude something to the Ccleaner process, we be able tododge the problem. And the funny thing is it only happens to some of them, not all.

Anybody seen something like this?

Thanks,

Were you scanning with the crap cleaner portion or the registry cleaner?

Definitely the crap cleaner. I doubt my consultant would use the registry cleaner without my prior knowledge. But that is a good question. I'll have to check.
