The step from 3.5 to 3.6.2 (or 3.7, for that matter) is not strictly an 
update, but installs as a separate piece of software, so those versions 
can live happily alongside each other. (It would be different if you 
already had, say, 3.6.1 installed.) I would actually recommend leaving 
the POV-Ray 3.5 installation intact, as the Architectural program may 
not work well with the 3.6 or 3.7 versions.

On a dual-CPU or dual-core system, you'll definitely benefit from 
POV-Ray 3.7's multithreading support. Even for a single-core single-CPU 
system I'd recommend it, due to various other improvements too numerous 
to mention.

(Just for clarity, the most recent POV-Ray 3.7 release is not labeled as 
beta anymore, but as "release candidate 3", or "RC3" for short; that's 
the one you want.)

POV-Ray 3.7 for Windows is available in both a 32-bit and 64-bit 
version. As there are no known caveats with the latter, that's the one 
you want.
