@karbonforms said in FAF Client: Nothing works.:

The requested operation requires elevation

Looks like a user permission error. Or security software is interfering.

Check the ownership of the files and make sure you can access them.

@magge Ownership of which files exactly? It's rundll32.exe trying to open default browser (I assume). I have no security software aside from Defender.

I would suggest all files related to the FAF Client. Begin with the whole folder where you installed it.

What?

How would file permissions of the "FAF Client" folder affect a running java process's ability to open a browser via rundll32?

There is nothing funky about the files permissions. But to be sure, I set 'Users' and 'SYSTEM' to Full Control. Unsurprisingly made no difference. Also the AppData folder is fully open to all groups as is the ProgramData path.

Well, if you are certain, everything is correct. You can try to change your default browser; Maybe it will narrow down the issue.

These lines suggest that you have insufficent permissions to run whatever was passed to rundll32, I'm guessing that's launching the browser
or
You haven't linked the FAF binary correctly.
