DR with x32 and x64?

Can’t seem to find it anywhere, but can a workstation with x64 render DR with x32 rendernodes?

No. See this topic:

I read that one, but I thought they where only talking about backburner? (i’m talking about DR)

good question.
I would also like to know about 32 bit plugins in Max 9 64. This is not good?
