Regardless of what Microsoft say, the botom line is that they don’t provide a driver for DOS programs to work on 64 bit machines. What they do provide (at least in Windows 7) is an XP emulator. I use this myself. It’s ok but then I only use it very Occasionally. Normally I use the Windows NV. What it comes down to is if your going to go for a modern OS, you need a mordern accounting package. That is NewViews 2.
