From what I recall, there is only a 64-bit version. I am pretty sure since the page:
has 64-bit only. I wouldn't have called that out unless I only had a 64-bit installer. Of the thousands of downloads, you are the first person to ask for 32-bit. Sorry.
regarding your baffle cooling question: I assume you mean can the new 3D conformal cooling feature handle baffles?
The answer is yes. You need to model the 3D channel geometry created by the presence of a baffle. There is not special baffle element type.
