ODBCFIX.ZIP contains a new CTL3D32.DLL. If you see a message box pop up stating that CTL3D32.DLL is not a valid Windows NT image, then you need this fix. See the README file in ODBCFIX.ZIP for more details. This tempfix should be included in the first Visual component FixPak for VisualAge for C++ for Windows V3.5, which will be called WTV301.
