Typically, the reasons for this error are:

1) Invalid product keys
2) Product Key already in use

In either case, Tom's Hardware does not support software piracy in any form.

3) You're entering the product key incorrectly. There are some simple errors made by just about everyone. Common numeral and letter confusion includes:

0 and O
1 and L
5 and S
6 and G
8 and B
