Error - System.InvalidCastException error when opening a map from the Map Control Console

Symptoms

When an attempt is made to open a map from the Process Navigator Map Control Console, an unanticipated System.InvalidCastException error is reported, and the map is not opened.

The details of the error will depend on the context in which the map was opened and the nature of spurious Registry data.

The error can occur through any action that opens a map, examples of which are:

  • Edit in Microsoft Visio
  • Generate Next Level
  • Export to HTML

Cause

These errors are caused by spurious Visio-related Registry data, which could be, but not necessarily, the remnant of an installation of Visio that has been removed, and replaced with another of a different version.

The following example describes a test set-up on which Visio 2007 was installed, but to which Registry information sourced from a Visio 2010 installation on a different PC was added. Although artificial, the results match those reported by others who have experienced the issue.

'TYPE_E_LIBNOTREGISTERED' errors

If the '4.e' key exists, but there's little or nothing within it, 'TYPE_E_LIBNOTREGISTERED' errors occur. For example, such errors were reported with an empty '4.e' key or when the '4.e\0' key was missing.

Solution

The Registry data associated with any absent versions of Visio should be removed. In the example used, that would mean the deletion of the '4.e' key, which includes removal of the Visio 2010 interop data. The mere presence of that key will otherwise lead to these errors. In addition, check that this key references the correct version of Visio, which in this test case would be:

HKCR\Interface\{000D0700-0000-0000-C000-000000000046}\TypeLib\

Version = 4.c
