2001i - version 15 compatibility
I have mathcad 2001i which I am finally forced to upgrade because it won't work on my 64-bit windows 7 computer.
Will mathcad version 15 open 2001i files (.mcd)? If so, will they be usable with minor editing or will there be a lot of work required to get them working right?
(I read that version 15 will not save in 2001i format so it makes me think that maybe it won't open 2001i files either.)
