SharePoint JavaScript Error: Library Not Registered

The other day one of my clients upgraded from Outlook 2003 to Outlook 2007.  Since then, whenever she went to her company’s SharePoint site, she received the following error:

Apparently the Outlook upgrade did something to a DLL (removed it?) that SharePoint needs.
If you have just upgraded from Outlook 2003 to Outlook 2007 and you receive a similar error, simply run Office Diagnostics and it should fix the problem!

To run Office Diagnostics follow these steps:
1. Open Microsoft Outlook 2007
2. On the Help menu, click Office Diagnostics
3. Click Continue, and then click Start Diagnostics
