When I attempt to "add files" to a project in developer studio, I get a dfdev.exe application error: cannot instruction xxxx at memory nnnn.
I've used this program for years with no trouble. I have the latest V6.6C. I suspect an incompatibility with one of the more recent Windows 2000 patches.
I erased all .OPT files
Removed the two suggested registry Keys
Uninstalled and reinstalled Visual Fortran 3 times
Any ideas? HP wants $250./hour to troubleshoot. I consider this an installation problem but they still want the fee.
