I do not understand why Labview 7.0 did not found the driver DFORRT.dll when I open certain of my VIs I have made with the 5.0 version. Is there a place I can download that driver ? Thanks in advance.
This probably means that one of your DLLs was written in Compaq visual fortran.
Do a google search for "dforrt.dll download" and you should get some matches (e.g. http://www.tu-harburg.de/vt2/pe2000/Download.html ). Good luck. (Else, let me know and I e-mail you a copy.)
