OCX Error 372  (Failed to load control)

Hi All,

We have a legacy vb6 app that is still running.  Every once in a while, we'll get a "failed to load control" <control> from name.ocx.  Your version may be outdated.

We are manifesting the file and there should only ever be one version of the DLL.

Other Factors:  

1)  We are running it off of a mapped drive
2)  Error most commonly appears when a user uses a different computer than the one they are normally logged into.

EG:  User A is logged off, User B logs in, runs app, error.

So far it's not consistently reproducable.  If we wait for a while (approx 15 minutes or so . . . and/or a couple of reboots) the problem goes away.

Information is coming from users so is sporatic and questionable at best . . . but trying to narrow down the places to look.

Thanks in advanced.

The user(s) could copy the "application.exe" and the .ocx file to a local folder and then run the copied exe (and the copied .ocx) from that local folder.

We're trying to avoid that for easier publishing and what not.  This works for a bunch of other apps but for some reason this decides to bomb . . . some of the time.

Nice suggestion CC; but after some more digging we found that a dependant component wasn't being loaded which we believe was causing the issue.  We're waiting to see if the error message comes back up.

To get informations about the running processes and all modules that are loaded by the vb6 program try  TaskInfo v10.0.0.336  (2872KB). The program is for Windows and free for personal non-commercial use.

Was an issue with one of the dependencies of our component causing an issue.
