Hello,  
What is the procedude to have 1.5 and 2.2 working on the same workstation with 3Dsmax.  
I face some rendering time problem with the 2.xxx version and for test purpose I need to render some test scene with both version.  
Uninstalling each version and installing them again is a real headeach.

Thanks  
Fraggle

I had no luck with this, so I made a second user on my machine that has 1.5.

Use different versions of max if you can for different Vray versions. We keep old Vray on Max 9 and the new Vray on max2011.

Thanks,  
All my soft are installed on the admin account (I chosed to installed it only on admin account).  
Does it means that I have to installed max again to be able to run it with another account?

By the way, I don’t get the point, how to you split v1.5 from 2.2 from one user to another one?

Thanks  
Fraggle
