Not sure if this is what you did, but what I do to update is run wow.exe only on my primary wow folder, let it update, then simply copy launcher.exe and wow.exe to my 4 clone installs (which have junction points). This is all that is needed due to the fact that everything in data is already updated from the primary install.
This is pretty much what i did!

After i copyed the wow.exe and launcher.exe everything worked, i messed around alot so im not 100% on everything i did since this message popped up on my main aswell.

Took me about 3-4 hours in total to fix the wow patch and macaroon, guess im one of the lucky guys today!
