Lightroom 5.7.1 and move to Windows 11 machine
Just moved Lightroom over to a new Windows 11 PC. Loads ok (after installing a needed DLL) but prompted me for the licence code. Went into my Adobe account, retrieved the code and entered it, only to be told that this is an upgrade code and I would need the original as well. This, apparently isn't shown on my account. I have had this software for many, many years and several house moves and the original box has gone the way of many things. I don't understand why the upgrade code isn't sufficient proof, but any help appreciated
