I am getting this message from ccleaner.
Support tells me I have installed ccleaner professional on too many computers. I actually haven't. I have installed it on new computers after removing it from old, out of use, computers.
I am really annoyed that ccleaner just invalidated by license (with six months left) without asking me for an explanation. What happened to "innocent until proven guilty"???
I think I'll just switch to the free version and never pay anything more to piriform.
