Have updated windows 7 32 bit to 64 bit and have reinstalled lightroom 5 and need a serial number, How do I find it?
If you originally registered your product the serial number will be stored in your Adobe account. Click the red logo (top left on this web page) sign-in, and then click the Manage Account button. It should be possible to browse your purchase history. You are looking for a 24 digit number commencing 1160.
Many thanks, all fixed. GH
