Problem moving RW5 to RW6

I am in desperate need of help.

I have to say, that I am not computerlitterate, so please explain so what even someone quite slow can understand it . thank you :smile:

I have downloaded rw6 and migrated all my plugins to it. But when I follow the guide, and press file and then open, it opens a page where rw folder is. Plugins are all greyed out so to speak, all the folders are visible clear but the open prompt is greyed out and can’t be used…

What am I doing wrong?
