Hi,
I downloaded that autoruns tool and ran the gui version. So from your post you suggest running it, then finding the two missing .dll entries (gvavi.dll and ntlsv39.dll) So to find them I run the autorun tool then click on the know DLL tab and locate them, then delete them. Doing this all from the user account that is having problem, not the admin.
You also said not to use a registry cleaner, why is that, or do you mean don't use a free one. I thought a quick fix would be a registry scanner to fix those missing .dll files.
thanks,
jon
