I installed a SPSS Statistics V 25 on a computer and created a new authorization code in the SPSS License Key Center for this installation, but i never got the add feature button in the second creation step. So i created an authorization code for SPSS Base V25 and took an authorization code for SPSS Regression V 25 (not activated but already generated before, i don't know why and by whom). The problem is, i can't activate both codes, only one code which excludes the other feature. I can only activate SPSS Base V25 or Regression V25, but i need Regression as an additional feature to the Base license. I also tried diffrent browsers, but i never got the additional feature button to include the feature in the base license authorisation code (like described in your help sites). The last thing i read in forums was, that you can't use the "Add Feature to your installed Statistics" for combining a feature to an already existing code.

Please help me with this strange problem.
