Have you purchased an upgrade serial or did you download the trial version (a) perpetual license or (b) Creative Cloud version?
It is not possible to simply "update" from Lightroom 1 to Lightroom 5. This requires an "upgrade" which must be paid for. You will need a separate serial number for Lightroom 5. And if you purchase the upgrade, installation will require both serial numbers.
Thank you so much for your quick reply.
Yes, I had purchased an upgrade to LR3 and was mistakenly using my original LR1 serial number instead of the upgrade serial # from LR3 to upgrade to LR5. Does that make sense?
Well, this was my first query to the community and I appreciate your swift response!
Thanks for all!!
Good to see that you got it sorted out. Enjoy the program.
