Paul, >Virtual PC 2007 will not normally install under Windows 2000 but there is a simple procedure on the internet to edit the MSI installation file so that it will not refuse to load if it detects w2k. It uses a program called Orca and is extremely straightforward. Afterwards, it will install and, so far as I can see, it runs perfectly. Interesting. The ability to edit MSI files would be helpful in many instances. Where can I find this procedure? I gather Orca is part of Microsoft Windows SDK for Windows, which is enormous. What do I need to download in order to edit MSI files?
