Upgraded from LR5 to LR6 (downloaded version). Installation went fine and LR6 generally seems to work OK; however the "Help" feature does not work. Any attempt to select "Lightroom Help ...(F1)" from help menu results in "This page can not be displayed." Using F1 key produces the same result. I have a broadband web connection and internet access. No problem accessing the web. Just can't seem to connect to the LR help site. Any ideas?
I tested on Windows and Mac and there appears to be a server problem or bad link in the application.
Adobe needs to provide a fix.
You could file a bug report but in the meantime the pdf format is available at the following link:
