I purchased PC Reviver for my HP Laptop. This is the first time I am using the program, which I purchased in Dec. 2016. I scanned my computer and am at the point where I'm trying "clean" my system. When I click "clean" I[m told to put in my License Code, which I did. Then it tells me to put in a correct code. What am I doing wrong.
Operating System:
Windows 10
