To run the DVD on a Windows 7 PC, one need to set up a virtual machine that runs in Windows XP mode. I have Win 7 Professional and the DVD runs under the virtual XP machine. http://www.microsoft.com/windows/virtual-pc/default.aspxThanks skinnyb. Given that there are two varieties of manuals I was curious as to which one was "best". It looks like Bentley has stopped updating the DVD based manuals as they only support Windows XP. I'm sure the paper manual will be more than enough for me. Now I just have to find a DSG filer adapter that I can get shipped to Canada.
