I wasn’t sure if uninstalling the previous version was necessary. Support explained the correct procedure step by step.
When I entered my license key the software returned an unknown error code. I contacted support and they explained it sometimes happens if the installation wasn’t completed correctly. After reinstalling the program, the activation worked normally.
My first installation attempt included a small mistake. Support showed me how to correct it easily, and their professionalism made the whole situation smooth.
