The installation requires My name, Company's name and the ID of the product. I add everything, but still have "Invalid product ID". Do you have any suggestions?
I've found the solution, I should have added the SERIAL NO.
The product is not free and the registration requires all the details you have received from the developer of the application. Make sure you keep the serial number in a safe place.

You should be able to provide the payment proof, in case of recovery.
