Launch a new istallation from original disk over the same directory, after the patch will install correctly. Beware: make a copy of all default directory of the game you have modified by installing modding features, let say customized races shipset, ModPack, etc.
Beside if you have current games involving ModPack or customized races shipset some problem could arise after installing patch 1.35, it could be better waiting for new modders releases compatibles with the new patch before installing it.
