we inserted the new license on the pdfcreator v2.4 for a TS (windows 2012 R2).
the online activation did not work so we did the offline one.
The issue is that the product is not activated for all users. some of them are getting the old license.
I am afraid some older versions still handle the activation per user. You can either copy the license and LSA entries from HKEY_CURRENT_USER\SOFTWARE\pdfforge\PDFCreator to HKLM\SOFTWARE\pdfforge\PDFCreator (from the user account you used to activate offline) or update to the latest 3.0.1 release, which stores the activation machine wide in the first place.
