To fix it:

1. Whitelist the folder: Go to Windows Defender or your AV settings and make an exclusion for the Nemesis folder.
2. Re-extract: Delete the current folder and re-extract the latest Nemesis zip file directly into your Skyrim directory.
3. Run as Admin: Right-click the executable and run as Administrator.

   • For Vortex: Install as a normal mod, then set it as an “Engine” tool.
3. Add Nemesis as an executable in your mod manager.
4. Run via the mod manager (not standalone) and as administrator.
