Shell function to call .exe

Hello,

I have recently been using the following code to call a .exe in the same location as my workbook.

Shell (ActiveWorkbook.Path & "\myfile.exe")

This works fine when I run it on the C: drive.

However, if I move the files to a network folder (the workbook and .exe are in the same folder), VBA returns no errors but the .exe does not run correctly (the .exe is a fortran code with text outputs. It appears to run but produces no output files).

I can run the .exe by clicking on it no matter where it is and it produces correct outputs. It's only when I try to call it with Shell that it doesn't work.

VBA also appears to have no permission issues, as it happily creates folders and copies files around on the network drive or any drive for that matter.

Even more bizarre, when I call the .exe from VBA in a network folder, the .exe appears to run, creates no outputs in the folder it should, but in fact creates phantom (blank) outputs in the "My Documents" folder.

I hope I explained that well enough. Please let me know if there is a way around this, because ideally I would like users to just copy this package (workbook and .exe), share it across network drives and for it to work anywhere.

Thanks,

Vlad
