Error: "MetaMate: Couldn’t obtain plugin principal class", How to solve?


I just ran RW7 (7.1.7 to be exact) for the first time in a while and received the error message:
“MetaMate: Couldn’t obtain plugin principal class
Would you like to check for updates?”

I press the “Update Plugins” button and, as far as I can tell, nothing happens. If I quit and re-run RW7 I get the same message. What does it mean and how do I solve it?

(For what it’s worth, I have also updated to the most current version of RW7 and I am still getting the message.)


MetaMate is not updated to work with RW 7, and it will not be ready for a while.

Good to know… Should I just ignore the error message in that case?


I would remove it from your addons for now.

Will do. I actually don’t see it listed in the “Manage Addons” window of RW7… Is there another way to remove it from within the application, or must I do it manually (ad if so, where do I look for it)?


@NeilB – I had this same problem with CodeComplete and MetaMate in Rapidweaver7. Here’a link that helped me find how to access and delete those manually:

Ultimately, I pressed command + option + 7 and it opened right up. Hope that helps.
