I guess I am fortunate I have no installation issues with Vue 6 Esprit with modules, as I installed Vue with Administrator Privledges into Vista x64.  As agiel states if you have the NVidia Drivers there are two versions under a new beta that will resolve most of the current issues with Vue, the others issues are minor and should not bother the app.  Check out the NVidia Beta drivers 101.4 for x86 or x64. 

The only problem I am having with Vue is Subsurface Scattering materials cause a massive memory leak when rendering, which casues Vue to lock-up and the OS to stop responding.  Remedy, I do not use the materials, and Vue works fine otherwise. 

My recomendation would be to purchase Vista Ultimate which is the x64 version and install at least 4 to 6 gigs of ram for best performance.  

Another thing that is important when installing Vista, you must have the latest hardware, ACPI compliante, prefereably within the last two years, and it all has to be x64 compatible. Vista x64 will also install and run 32 bit x86 apps, they just do not get the speed and memory advantage that a 64 bit app does.  Check out Microsofts Vista web site for compatibility issues.
