I'm working on VISTA64 ultimate with 3DSMAX2009 64 and VRAY 1.50sp2
At the bottom of the solidrocks window, it's write : VRAY VERSION : ?? Cores:8

B052 is working well

EDIT : Sorry Peter, logged by mistake with your account. but it's subburb here "

ok noticed
it cames from the demo_SP2 version

I'll correct that quickly
I tell you informed !

Many thanks

Same as above...

gosh!, that was quick...do we have a life? LOL : ))
