I have been using LR 2.6 with Adobe CS3 with success, ignoring the error message about not forwarding well to CS4 raw converter.
Yesterday I installed a trial version of CS4 and, in the process, somehow a Common File got damaged (and CS3 wouldn't save, etc)so I had to repair CS3.
Now LR2 says it can't open CS3 (although CS3 does get opened.)
LR2 is not seeing CS4 at all.
CS3 and CS4 are functioning fine.
I can make this work by installed CS3 as the secondary editor but this involved more work as LR turns the NEF into a TIFF first.
Frustrating, maddening.
Any ideas on how to make this work again?
TIA,
Lew
