3dsmax 64 (on vista) with Vray 1.5 licence problem...

As vista 64 seems to be a runner I installed a system for testing…

So, it’s 3dsmax 9 SP2 64bit with Vray 1.5 Rc4

PROBLEM: Everything worked till I came to the dialog where I had to choose the licence server. Vray prombt me an error: ‘Couldn’t write to licence file’ when I close the dialog.

NOTE: 3dsmax 9 SP2 32 with Vray is already installed on the system and runs perfect.
