How to get old help back?

the help option on the tool bar takes me to a wiki file. Which is useless to me. I downloaded the offline help but it is not recognized by my installation. Is there some arcane method to get the offline help?

another issue is that my currency format was showing as light green instead of red. I reset highlight and it went back to red. now those numbers don’t print. I must be something like a switch or misunderstanding of what highlight does, but there is no help so I can’t fix it myself. redundant bug. any ideas appreciated. Al
