I have been using CC Cleaner for about four years and have really enjoyed it. I was thinking about upgrading to the Professional version but I have a couple of questions. I have three computers running the free version and I wondered if I purchased the upgrade will I need to purchase three? Also, is this a onetime fee or is the an annual fee?
The pro allows for one installation only. for a year after buying pro you get priority support (so you don't have to deal with this user forum) and automatic updates. After that year those two things cease but all other pro features (multi-user, browser monitoring) remain.
