Outlook Error 'Could not load an object'

When you try to open an item in one of the Microsoft Outlook programs that are listed in the "Applies to" section, you may receive the following error message:
Could not load an object because it is not available on this machine.

There is a reference to an ActiveX control in the item's form, and you do not have the appropriate library files for that control registered and installed on your computer.

To resolve this behavior use either of these two methods.

Method 1
Click OK to the error message. The item should open without displaying the problem control.

Method 2
Contact the author of the form to determine how to install and register the control on your computer. This method may involve installation of an additional program that provides the control.

I hope it is useful for Outlook Support...
