The following error message appears when you attempt to use
your Visual C++ control in Microsoft Excel 97, Microsoft Excel 2000, or Microsoft Excel 2002:
Cannot insert object
Back to the top
This error occurs if you created a control in Visual C++, manually changed
the _wVerMajor and/or _wVerMinor variables, and didn't change the
corresponding type library version number in the .odl file of your project.
This occurs because Excel 97, Excel 2000, and Excel 2002 explicitly check to see if these two variables are equivalent in the registry.
Back to the top
To resolve this problem, you either have to change the version() attribute
in your .odl file to reflect the current state of the _wVerMajor and
_wVerMinor variables at compile-time, or specifically modify the registry
entry HKCR\TypeLib\<Your TypeLib>\X.Y, where X and Y represent your major
and minor version numbers respectively.
Back to the top
This behavior is by design.

For more information about the wVerMajor or wVerMinor global constants,
search for "wVerMajor" or "wVerMinor" in Visual C++ Help.
For more information about ODL (Object Description Language) files and the
version() attribute, search for "ODL" or "ODL Attributes" in Visual C++
Help.
