RT31037 "Error Loading From File"

Most likely you don't have the correct version of the file "tabctl32.ocx" registered. Or the file was installed in the wrong directory. Unregister your current version, copy the file "tabctl32.ocx" that comes with DynamIP into your ...Windows\System directory, and then register this new version (see instructions here).
It is also possible that the DynamIP installation program copied some files to the ...\Windows directory instead of the ...\Windows\System directory (see Required Files for a list of files and their installation directories).
As a last measure you can try the following:

1. Uninstall DynamIP.
2. Unregister the 7 OCX files used by DynamIP (cmuTCP.ocx, mscomctl.ocx, comdlg32.ocx, ntsvc.ocx, richtx32.ocx, tabctl32.ocx, xTFtp.ocx) [see instructions here].
3. Delete these 7 OCX files.
4. Reinstall DynamIP.
5. Start DynamIP.
