Pradeep,
I was able to properly run both my XDS200 and XDS560v2-class emulators on my VMware workstation 8.0.6 (and its counterpart VmPlayer 4.0.6), therefore my previous suggestion may be suitable to overcome the issues you are having with Vista. The reason I am not 100% sure is that I couldn't test it with a Vista host OS (only with Windows 7 as host)
I updated the page I sent before.
Hope this helps,
Rafael
