I bought Lightroom 3 or 4, can't remember which, as an online download. I then upgraded to 5 with a CD. I registered the upgrade on my Adobe account and that's where the serial number is. I just bought a new iMac and am trying to install Lightroom. The system is asking for my original serial number which I don't have. The point is. If I have the upgrade registered with my Adobe account, shouldn't that be proof that an earlier version was on my computer??? I'm really stuck. Need some advice! Thanks

Hi John,
Thanks for your response, but if you read my first mail, it's the original serial number that I don't have. I bought the original LR as download and have misplaced the serial number. Is there any way to find it???
