Welcome. I hate to be the bearer of bad news, but... You are referring to the 1.6.4 version of the pack right? If you are then you should know the newer packs are not built for 32bit computers. They require 2+GB of RAM to be allocated to work best. The problem is 32bit Java limits you to 1GB max. There is no way around this on a 32bit computer. The only pack that was built to work on 32bit computers is FTB Lite2. Though it has been reported that some 1.6.4 packs like Horizon and Magic Farm 2 work well on a 32bit computer. For more info look here and the last post of that thread for the report of the 32bit computer specs that run the other 1.6.4 packs well.

The only way that would happen is if somebody installed a 32bit os onto it because it can't just change to 32bit for no reason.
