I purchased LR6 standalone upgrade, downloaded it, and installed it on my Windows 7 lap top with no problem.
It asked me for the LR6 serial number, validated it number and then a drop down box appeared for me to enter my LR5 serial number.
When I entered that everything worked fine.
I tried the same procedure on my Windows 7 desktop, but I don't get the drop down menu.
I don't have Creative Cloud on the laptop, but I seem to have Adobe Creative Cloud installed on the Desktop, and I can't uninstall it.
Adobe customer service could not help me.
Any suggestions wouuld be appreciated.
If you think you need to uninstall the creative cloud application, can you not do it from the control panel/programs and features?
