What can I do if I inputted the activation correctly, but the "Next" button is still grayed out during installation?
When you enter an activation key, please make sure that there are no spaces before or after the actual activation key entry and remember that it is case-sensitive. Also make sure that you have filled in all other required information.
Note: Some of CyberLink products require you input activation key during installation. You have to fill-in Company Name, Name and activation Key. Any empty fields make the installation program unable to proceed.
