Activating LR 6 Upgrade - No Serial Number

[a_ch1lles]

Hi all,

Recently bought a new computer and found that to license my re-downloaded version of LR 6, originally purchased as an upgrade to LR 4, I need the original serial number from LR 4 on the product box. I have no clue where that box is since I recently moved, and most frustratingly, have a perfectly good version of LR 6 running on my old laptop which I activated when I still had the old product box. Entering the serial number for the new download of LR 6 produces this screen:

Presumably requiring me to present the old code. Am I screwed? Would a transfer of LR 6 on my laptop to this computer be the solution? Please let me know.

Cheers.

Do you still have Lightroom 4 installed on the old computer? With Windows Explorer, go to C:\ProgramData\Adobe\Lightroom.

In this folder there will be a file named Lightroom 4.0 Registration.lrreg

Open this file in Notepad, and you should find the serial number. You might be able to find this file even if LR4 has been uninstalled.

The other option would be to log in to your Adobe account.

If you registered LR4, you can find the serial nunber there.

The laptop is a MacBook, any idea where I'd be able to find a similar file? Away from the computer at the moment so I can't attempt a fix until later.

Never registered the product so that's not an option unfortunately. Needless to say I'll never not register ever again.

If you do find what you need... write it down and put it in a safe place

I assumed you were on Windows.

For a Mac, try this folder: Library/Application Support/Adobe/Lightroom

There it is. I was sure had to be buried somewhere. Many thanks all!

See the link below for help in locating your serial number. If you registered your product the serial numbers can be recovered from your Adobe account.

You should also be able to retrieve the numbers from the OS registry on your Laptop, do a search on the internet.
