Problem applying the Harem Patch for Maoujou Re:build (魔王城Re：ビルド!)

I'm trying to use the Harem content patch on the visual novel 魔王城Re：ビルド! Maoujou Re:Build by astronauts sirius, but I keep getting error messages.
Does anyone know how to properly apply the patch?


EDIT: nvm, I solved it, have to move the Harem contents folder to the installed game folder and run the Harem shortcut there
