Download PCA

Download the latest version of PCA on Nexus mods and extract it anywhere you want. It is not recommended to install PCA inside a directory that needs admin privileges (mainly Program Files folder).


PCA requires Creation Kit (CK) to compile your files. More ways could come later.

  • For AE/SE/VR/LE: CK is available on Steam. Download it from your Steam library in Tools section.

  • For FO4: CK is available on the Bethesda Launcher.
