Yaaay
Looking back, i'm still not sure why your download of 2.46 wasn't coming up with a .blender/scripts folder
I think i'm using a third party build of 2.46 though, and I'm not sure why i did that - perhaps it was because i ended up having similar issues finding the .blender/scripts folders? I'm not sure - it was a while ago.
I'm still kind of annoyed 2.46 changed texture baking somehow, and I never bothered to look up how to achieve what I was trying to do in the new version. As a result, I still keep a copy of 2.45 around for the rare times I want a bake from Blender.
