XP and 32-bit is dead
32-bit actually came out late 80's/early 90's -- surely your software is newer then that
i jumped to 64 bit as soon as Vista was out, never looked back since
1) just because a software is new does NOT mean that it's x64 - most software coming out is still 32-bit.
2) Just because XP isn't supported doesn't mean it's dead. As to 32-bit being dead as a format, my only possible response is to ask what you're smoking - just because you switched to it doesn't mean it's dead. The majority of prefab computers being sold right now are 32 bit windows 7/8, not 64 bit.
