The dos version of edit.com is a 16 bit program and will not run under a 64 bit OS. Just use notepad or something instead of edit.
dude just get dosbox for X64 and X32 Cool right look at an image of my little thingy,ma,bob sorry the image i could not use go to http:// and download it FREE!!!
On a 64bit machine I would use Notepad++. It is the only program which could convince me to leave vi. Hope this is not against the rules of the forum...
