Having purchased a new computer I've attempted to install LR6 on the new machine but keep encountering the same problem.
I've downloaded the LR6 software from Adobe and get as far as entering a valid serial number which comes up with an error message saying serial number is valid but a qualifying product could not be found on this computer. In the same window there is a pull down with qualifying products displaying Lightroom 1 through to Lightroom 5, there is no option for Lightroom 6.
The valid serial number I have is for Lightroom 6.
Am I missing something and can anyone help?
You have purchased an upgrade version. The upgrade version requires that you have a serial number for a previous version (Lightroom 1-5). Installing a Lightroom 6 upgrade needs both the serial number from a previous version as well as the serial number for Lightroom 6. If you have a previous version installed on your old computer you will need the serial number from that version.
Thank you Jim, this solved my issues. LR6 up and running with correct catalogue.
