Hi -- I just upgraded from LR3 to LR4 on my Windows 7 HP notebook, using a CD from B&H Photo. The installation process went through without errors. However, now in Develop mode, the editing tools (right side of screen) are still the LR 3--for example, Recovery, Fill Light and Blacks are under Exposure. I've restarted the computer to see if that would help--no change.
I suppose I could uninstall LR, then reinstall LR3 and the LR4 upgrade, but that's a lot of work and it may not resolve the problem.
Any suggestions for fixing this?
Also, what's PV2012?
Whoa - you are green....
In Develop module - check the Process Version in Camera Calibration section - change to 2012 (Current).
Alt-click is just a short-cut for doing the same thing, but without having to answer a prompt (in develop module, when an exclamation icon is displayed, indicating an older process version, like 2003 or 2010. PV stands for "Process Version".
2012 is the newer process version invented for Lr4 with improved controls and image quality...
