Different V-Ray versions on the same computer.

Just a question,

Is-it possible to use Vray 1.5 SP2 for 3ds max 2009 and V-Ray 1.5 SP3a for 3ds max 2010 on the same server ?
I want to upgrade my V-Ray but some productions are still ongoing with V-Ray SP2.

Best regards,

Léon

yep, I still have 1.5sp3 on max9 and 1.5sp3a on 2010. both work all right.
