I upgraded from LR 5.7 to LR 6.6; now LR does not open when I insert my media card. Under Preferences, General, I have the check mark for show import dialog when card is detected. Ideas please. Thank you.
What is your OS?
WIN 10 64, however, I think I got it.
I changed InvokeProgID to Adobe.AdobeLightroom64 - the 64 was not there.
Yep. Glad it works for you now.
