Form Controls stop working after December 2014 Updates

For some users, Form Controls (FM20.dll) are no longer working as expected after installing MS14-082 Microsoft Office Security Updates for December 2014. Issues are experienced at times such as when they open files with existing VBA projects using forms controls, try to insert a forms control in to a new worksheet or run third party software that may use these components.

You may received errors such as:

"Cannot insert object"

"Object library invalid or contains references to object definitions that could not be found"

"The program used to create this object is Forms. That program is either not installed on your computer or it is not responding. To edit this object, install Forms or ensure that any dialog boxes in Forms are closed."   
       * Note In this last error message, the Forms text may also be replaced by the GUID of the control.

Additionally, you may be unable to use or change properties of an ActiveX control on a worksheet or receive an error when trying to refer to an ActiveX control as a member of a worksheet via code.
