When you unzip/extract the mod you will have a folder named 'SfCRevamp_vXYZ'. Inside that folder is a folder named 'mods'. Copy and paste mods folder into %appdata%/Roaming/Strive for Power 2. This makes the path for the mod '%appdata%/Roaming/Strive for Power 2/mods/ScCRevamp'
If you extract ScCRevamp_vXYZ into the 'mods' folder then the path would be '%appdata%/Roaming/Strive for Power 2/mods/SfCRevamp_vXYZ/mods/ScCRevamp' which would be incorrect and would cause issues.
