I cannot edit Equation 3.0 objects in office 2013, stopped working an hour ago

I have a lot of documents with equations created using Microsoft Equation 3.0.

When I go to edit these objects now, I receive the following error:

"The program used to create this object is Equation. That program is either not installed on your computer or it is not responding. To edit this object, Install Equation or ensure that any dialog boxes in Equation are closed."

I have attempted to resolve this issue by do the following, but none of these work:

1. Running the quick repair, which results in the error "Microsoft click-to-run is not running" - which is incorrect because office works.

2. Installing the compatibility pack for word, excel, and powerpoint file formats (http://www.microsoft.com/en-us/download/details.aspx?id=3)

3. Trying to locate a Microsoft Equation 3.0 download, which doesn't exist.

4. Running the network repair, which seems to do nothing but prevent me from using office until I restart my computer

How do you edit equations created with Microsoft Equation 3. using Office 2013?

Answer
Answer

So, I have Office 2007 enterprise edition on a work machine, and it also produced an error initially. I used the Change->Repair option from the Control Panel, and that fixed Word so that I can now use Equation 3.0 again.

However, this indicates a more precise problem with my Office 2013. I suspect if I could implement a repair, Office 2013 would also support Equation 3.0. However, because I always receive an error when attempting a repair, I cannot proceed. I ended up uninstalling and re-installing office 2013, which fixed Click-to-Run and restored Equation 3.0 functionality.

I don't know exactly what the problem was, but it is fixed now.
