1. if you have entered the license key manually, please check your entry for errors first (too many spaces, hyphen forgotten, letter O like Otto instead of the number 0 and vice versa etc.). We recommend copying the license key to the Windows clipboard and then entering it into the relevant text field via "Paste" from the context menu to avoid typing errors. Please make sure that the license key you use belongs to the product you want to activate.
If you receive an error message during the activation process, please make sure that Internet access is not blocked by any security applications (virus scanner, firewall) installed on your system and adjust the settings for them if necessary.
If you receive a detailed error message with a check number during the activation attempt, please send it together with the license key you used by e-mail to our support staff at email@example.com .
