    Unable to validate serial number


      I have successfully purchased, installed and registered Lightroom 6 on my Mac desktop as a stand alone application.


      On the road and in the field, I use my McBook Pro, so I tried the to install Lightroom on it. No problem, until I tried to register. I enter my valid serial number (not signed in to CC) and I get a window saying: "We are unable to validate this serial number for Adobe Lightroom. Please contact Customer Support."lightroom regitration.jpg

      Seems to only way to get the program started is to use it as a CC application, which I don't want to do.


      Why is it not accepting my valid serial number???
