Need to reinstall on new computer
In 2013 I purchased LR4 from Newegg with a free download of LR5 upgrade.
It was down loaded with a product key and through time, updated to 5.7 (latest version of 5, prior to LR6 release)...
I had to replace my computer but I was never sent a LR5 disk and I have long since lost any paperwork that might have had a key code on it...
I know that I can download the program again (the site for that isn't with me so I can't reference it) but don't I have to have LR5 in order to upgrade it to 5.7?
Also, don't I have to have a valid LR5 key?
Am I stuck going back in time to LR4, or purchasing LR6?
I'm under the impression that LR6 doesn't play well with win10...
What can I do?
