How to fix Microsoft Outlook Error: Interface not registered

So I installed some video editing software, did some updates, and then BAM!! I can no longer send email. Whenever I hit send I get an error from Microsoft Word saying “Interface not registered” but then there was the internet… and I found the solution…

Solution is here at the MS site

If you use Microsoft Word as your e-mail editor in Microsoft Office Outlook 2002, and you try to send e-mail messages or to save e-mail messages to the Drafts folder, you may receive the following error message:
Interface not registered
Or, you may experience the following symptoms:
“¢ You receive an error message.
“¢ The e-mail message is not sent.
“¢ The e-mail message is not saved to the Drafts folder.

This behavior occurs if the Ole32.dll file that is located in the %Windir%\System32 folder is not registered correctly in the registry.

To resolve this problem, register the Ole32.dll file. To do this, follow these steps:
1. Click Start, click Run, type the following command in the Open box, and then click OK:
Regsvr32.exe %Windir%\System32\Ole32.dll
2. In the RegSvr32 dialog box, click OK.”

In microsoft outlook, interface not registered = a most sucky error
