Before updating the key, please make sure you have the last version of the appropriate software installed.
The registration key is attached to computer hardware and sometimes Windows version. If you have upgraded some your hardware, bought a new computer or for some other reasons your unlock key does not work anymore, you should update the license key. To start the free updating process click 'Next' button.
After activation of a new key the old key will not be supported in new versions of the program.
