Presumably that mentioned installed folder doesn't actually exist, right?
So the bug here is that the "browse installed files" button should not be clickable until a Thrive version has been installed.
That can probably be done with a pretty simple check when opening the settings (or when the install location has changed) to see if the target install folder exists or not and set a view model property that disables the button if it doesn't.

Yep

I would disagree, the button should be clickable, the folder should be attempted to be created on launch. And warn the user if for whatever reason it can't be created.

And attempt to create it, if creation fails a flag can be made to warn the user.

I disagree. The launcher is used for example for Steam and itch.io seamless mode. The launcher should not create extraneous folders that may never be required by certain users.

It was even back in v1 that the install folder is only created the first time a Thrive version is attempted to be created.
