I am have no luck trying to make a render cow work for my main pc and render pc which are both running Windows 7 64 bit (see other posts in forum on this I have).  I am wondering if I should just go ahead and pay to get Vue 8.5 Infinite upgrade but the problem is I'm worried I will still have the same problem there based on the below e-onsoftware problems I found:

Is anyone in this forum using the rendercows for Windows 7 64 bit with Vue 6 Infinite successfully? How about with Vue 8.5? Who has it working with 8.5 on all PCs being Windows 7 64 bit?
