Could not use configuration settings (uninstalled game)

[Muckifant]

Heyo.

 

So i am trying to properly follow the written guide on their page to install the Tale of Two Wastelands mod for Fallout New Vegas.

 

Now on the "Choose Instance" window, that appears when one starts MO2 i want to click on "Portable" instead of "New" to use the MO folder instead of creating a new instance.

When i click on "Portable", i get that error message, saying that it "could not use the configuration settings for game "Morrowind"", and then the path where i had Morrowind installed some time ago. After that it wants me to direct it to a Morrowind intallation to manage.

I want to remove whatever MO2 has to do with my old Morrowind installation so i can use that "Portable"-button for Tales of Two Wastelands, but i don't seem to find an option for that.

What could i do?
