Hi Elbond14,

 

If you still have issues even after following the instructions, then I would suggest you to try the steps mentioned below.

 

Repair PowerPoint 2007 on your computer and then try to update

The Detect and Repair feature that was included together with Microsoft Office 2003 has been replaced in the 2007 Microsoft Office system with Microsoft Office Diagnostics. This new tool provides more comprehensive testing and repair capabilities. To repair PowerPoint 2007, follow these steps:

a.    Click theMicrosoft Office Button, and then click PowerPoint Options.

b.    ClickResources.

c.    ClickDiagnose, click Continue, and then clickStart Diagnostics.

 

Now try installing the update and then check if you’re able to install the update.

 

Hope this information is helpful and let me know if you need any further assistance.
