I had LR 3.6 and downloaded & installed the 30 day trial version of 4.0. Next I installed the two updates candidates which installs over the top of the trial version that was installed.
I have now purchased the upgrade version of LR4 with the license number, but not installed it.
I plan to continue using the already installed version with the updates until Adobe finalized LR.
Now my question: When the final version is finalized can I just use my serial number on my current installed LR4, or do I uninstall the current LR4, then install from the DVD with serial number and then install the updates again?
I still have 3.6 installed. I am also concerned about loosing the new catalog from LR4 since it has many more photos added since copying from the 3.6 catalog.
If it matters I use Windows 7 on a laptop.
