Persistant addon installation prompt

I’m trying to install the stacks 3.5 update. RW (RW 7) keeps asking me to update every time I open RW. I read about this a few days ago here but cannot find the original question or post.

May someone please provide me with, or direct me to a solution.

Thanks in advance!

Best thing to do is to go onto Yourhead’s slack channel and ask about it there:
