Hope that gets someone's attention. I have used Lightroom since the original software belonged to someone other than Adobe. My first Copy of LR was version one which I received free because I had purchased a lifetime subscription to the software that Adobe bought and converted to Lightroom.
Now I have a subscription to CC and cannot get the LR update to version SIX to run after downloading and installing. This happens with every LR major upgrade (such as from 3 to 4, 4 to 5, and now 5 to 6). Seems like it would at least work in the CC version.
After downloading and installing LR6 I get this message when trying to upgrade: "Lightroom.exe - System Error: The program can't start because amtlib.dll is missing from your computer. Try reinstalling the program to fix this problem." REINSTALLING DID NOT HELP!" WHERE SHOULD I GO/WHAT SHOULD I TRY NEXT?
