I have three versions of Hearts of Iron 2 on my machine. The first is the vanilla version of HOI2, version 1.2. I have two other versions of HOI2 1.2 installed; one has the Stony Road mod, and the other has the TRP mod. I would like to download the latest Paradox patch for HOI2 and just update the vanilla version of HOI2 (1.2) because saved games with the other two modded versions aren't compatable. How do I avoid the installer from installing the patch to EVERY version of HOI2 on my machine?
