Dear All, I use to run a local installation of Mathematica 8 on a Windows 7 machine. To "talk" to an external program (dos executable-> myprog.exe), I used the following code: command = "myprog" <> macro; LinkOpen[ command] Probably this is not the most elegant solution but it worked! Now I am running a remote installation of Mathematica 8 on a windows xp machine and the same command does not work anylonger. The error I get is: LinkOpen::linke: Could not find MathLink executable. >> and a window opens that asks me to "Choose a MathLink program to launch". Can anyone help me with this? thanks, Luigi PS: I have also tried Run[command] but no results!
