Why doesn't Open/Create... work with Exec?

[dgholstein]

The attached VI reads an EXE file and feeds the results to "System Exec.vi" -- it doesn't work.  When I write the same string to an INI file, retrieve and pass it back into "System Exec.vi", it works.

What's up with that?

You should not be trying to open the file as if you were going to edit it. All you need is the File Dialog function to get a path.

There is no reason to open the file, but if you do, you should close it before calling sytem exec (or open the file in read-only mode). This eliminates the error.

Of course the right way to do this is using a file dialog (as Dennis already mentioned). See attached (LabVIEW 7.0).
