So I am getting this error. Error Code 4: Your Papyrus INI settings are invalid...
This is a fresh install. Steps that i took.
1. Downloaded skyrim
2. Ran once without mods or any alterations
3. Installed SKSE (used installer straight from their webpage)
4. Ran once to check if SKSE worked (It did obviously)
5. Subscribed to SkyUi
6. Ran launcher once to download the mod
7. Ran SKSE_launcher.exe- got the error.
8. Edited Skyrim.ini in C:\Users\Wilsas\Documents\my games\Skyrim
9. Ran game again- same error.
There is another thing. My MCM settings list is empty. I assume that it wont be empty when papyrus ini settings are sorted.
