I think it would be nice if the user could get the key directly from my website and send the request for a license key straight away, instead of first open the actual workbook which can not be activated anayway before they have the license key.
Its just to make the activation process more user friendly (my opinion ofcourse).
I have also looked into the onlie activation key for a trial version but this does not work. If I want to give 30 days of trial period,- they can reactivate the workbook for another 30 days as soon as the trial period expires.
