Hi,
removing the two folders did help.
(Actually the FAF folder wasn't deletable in any way so I just renamed it)

I can now launch FAF normally.
Thank you for your support:)

Yes, I did restart my pc. After that I looked for files named with avast and I removed them too.

Still didn't work unfortunatly, I did remove Avast and I reinstalled FAF.

Here's the error message
java.lang.RuntimeException Exceptio.txt

My pc runs on windows, Edition Windows 11 Pro, Version: 21H2 and I'm using Avast Free Antivirus.
My pc is still at version 21H2 and when I check for updates there's nothing new shown. Last time I tried installing such an update it didn't work. Could that be a problem?

The Error message
java.lang.RuntimeException Exceptio.txt

Whats next to do?

There's just a client.prefs file in
%USERPROFILE%/AppData\Roaming\Forged Alliance Forever\
i'm not able to drop into this box:

[client.prefs](Invalid file type. Allowed types are: .png, .jpg, .bmp, .txt, .log, .gif, .webp, .csv, .pdf, .xls, .doc, .zip, .7z, .rar, .dds, .jpeg)

There aren't any hidden fils as well, I have this programm called TOTAL CMD64 which would show me any hidden fils.

I'm not sure if this helps buthere is the Text from client.prefs:

Unfortunately it didn't work, there is still the same pop up with Startup Error with the text again as long as before.

Before I installed Supreme Commander FA I had problems with launching the first version of Supreme Commander, that's why I bought SC FA which works.

Does this problem perhaps also have something to do with this?
Or what else could I try to run FAF?

Thank you for your support @MostLostNoob

Hello there,

I just bought Supreme commander FA today and I installed FAF. After the installation opended FAF and I could see the loading screen for a few seconds, then it crashes.

The text is quite long and I dont understand anything.

Does anyone know a solution?
