1.3b download

[Castellon]

1.3B is an AI update not a self installing patch, so you must uncompress it to the HOI2 folder. You can find it in a sticky thread in the Generql discussion forum.
As for your trouble with the user mod, I have no idea, We do not support user made mods. Please contact the makers of that mod for assistance.

You can use any program capable of decompressing RAR files, I use WinRAR.
You extract it to the main HOI2 folder, which if you used the default path would be something like C:/Program files/Paradox Interactive/HOI2/
