Same problem here. Anyone found other solutions? If that Longbow Converter can make it work, why is AutoDesk itself not making it easier for us right now. I know the solution should be coming from my plug-in seller but then again... they don't/can't.
They do have another new program that substitutes the program we are still working with but we would need to change our entire environment for that... and it will cost a lot of money. (Almost?) impossible at the moment!
Can't AutoCAD make the version work 32-bits on a 64-bits windows 7 machine for the time being? Why don't they do that?
I think installing a virtual windows xp pc, buying another program to convert AutoCAD and that sort of solutions are not the solving of the problem I seek. They are all work-arounds for a problem that perhaps could be solved easily by AutoDesk itself?
