All you need is the serial number from LR 3 when you install and run LR 4 for the first time, you also need the serial number for LR 4.
Once installed when you run/open LR 4 for the first time it will ask do you want to run a Trial, Purchase it or enter a serial number. You select enter a serial number. Once you enter the Upgrade serial number for LR 4 it will ask you to enter a serial number from a previous version. you then enter the LR 3 serial number.
Next time you want to upgrade OS X please check that all the software you have installed on your Mac will work with the new Mac Operating system.
Thanks for your help unfortunately I do not have the serial number for LR3 bought it online and installed it online. I do have the LR4 upgrade serial number if that helps.
The LR4serial number is 1160-4002-9006-9204-5123-6023
I am considering upgrading and hope you can help.
That won't work as all Upgrade serial number require either the older, previous, version installed or the serial number from it.
Since you have the LR 4 serial number you can go to LR 5 (If you can find a copy and if you want that slightly older version. NOTE there will not be any more updates for LR 5) or LR 6.
But you can get around all of that if you do the subscription base service and then you would also get Photoshop.
It isn't a goo idea to post serial number on open forums.
This is a public forum, so never post serial numbers.
Not sure if you will be able to edit your post after I replied, if not, a moderator will hopefully remove it.
Since you bought LR3 online, you must have received an email with the serial.
Hopefully, you still have that email.
If you registered the program with Adobe, you can find the serial in your account.
I don’t have that email. I am thinking that probably was at least 5 years ago. Then I upgraded to LR4 with a disc. I was hoping their was away to recover the serial number.
As a wild stab in the dark, hoping that the upgrade didn't wipe everything out, have you looked in here to see if the following file is present?
/Users/[user name]/Library/Application Support/Adobe/Lightroom/Lightroom 3.0 Registration
If you find it, you'd need to open the file with a text editor to see the serial.
Okay. I will try and the email, but I think because it's so old I probably won't find it.
I'll look into the subscription with photoshop.
I deleted the email with the serial number. Thanks for your help.
