Modo is 32 bit for now, yes, but purrs on a 64 bit. Believe me, it is amazing how fast it is when installed to a 64 bit os. I use XP64.

Modo will be 64 bit. I was told that by Luxology on the phone.They are working on it right now but was not sure when it will be released. 302 is on it's was soon. Maybe it will come with the 64bit update too.
