As I said earlier: There other possibilities you might want to explore: Running Virtual PC 2007 on Windows 7 (the blog of V PC developer at MS): http://blogs.msdn.com/b/virtual_pc_guy/archive/2009/08/19/running-virtual-pc-2007-on-windows-7.aspx This contains the pros and cons quite extensively. I would suggest to skip the XP mode altogether and run a separate Virtual PC 2007 program with DOS 6 installed in it. Select the 64 BIT/setup.exe http://www.microsoft.com/en-us/download/details.aspx?id=4580 DOS applications run very well under this environment. How to install DOS additions, see my page and look for the "DOS Additions" download (MS-supplied version is not compatible with DOS). http://www.lexitec.fi/xywrite/utility.html Best regards, Kari Eveli LEXITEC Book Publishing (Finland) lexitec@xxxxxxxxxx *** Lexitec Online *** Lexitec in English: http://www.lexitec.fi/english.html Home page in Finnish: http://www.lexitec.fi/
