Yes,I just put up with Win 10,as access to the internet,to misquote a line in "American Graffiti"....what a waste of technology ! I am sure I tried installing dosbox on my win 7 machine but no dice ! (to run the original "Silent Hunter"....yes I love old technology !) I will try again,because it would be nice to run them on the Win7 machine. Thanks for the info.
