Registration Troubleshooter
Registration codes will work only for a specific major version and platform.
For example, codes for version 6 will not work with version 7. Also, codes for Mac OS X will not work with Windows (and vice versa).
If you have legitimate registration codes for an older version, and you want to upgrade, you are eligible for an upgrade discount. Please click here for more information.
