Hi @s.doig - I agree with you re: using MainWP, but this isn’t an error I’ve ever heard mentioned by other users.
The path Nick mentioned above is just the path to wherever Local is installed on your machine. I can’t tell you where that is, unfortunately. I am also using a 64-bit version of Windows on my machine - below is a picture of my C:\ drive. Local and the files it ship with live in Program Files (x86)\Local
, which is where other apps on my machine (Chrome) are installed too. Have you checked your Program Files folder? What does your C:\ look like if you’re not seeing Local there?
