Original GitHub issue: https://github.com/SillyTavern/SillyTavern-Launcher/issues/15

I use Windows 11, I installed SillyTavern and the extras via the Launcher. I didn't install (I chose "N") coqui as it asked me if I want or not.

When I start SillyTavern with extras, then I get an error in the Extras Shell:

I fixed the Problem as I deleted the module in the Launcher.bat. It was really good hidden. I think it's still a bug, because at the installation it asks if you want to use coqui or not and even though you selected "no" it still tried to start with coqui, because the parameter was still in the Launcher.bat.

A second file for extras start parameter would also help. Then it is easily editable.
