Office 2013 - Updates are ready to be applied error message.

Updates for Office are ready to be applied, but are blocked by one or more apps.

I have a customer who is getting the following error message in Office 2013. “Updates for Office are ready to be applied, but are blocked by one or more apps.”

Office 2013 - Updates are ready to be applied error message.

 

The problem is when the Update Now button is clicked, you get a notice saying you’re up to date! Restarting the program will bring the error message back again.

Office 2013 is up to date

 

I haven’t found a good solution for this problem yet, any ideas?

I’ll update this post if I find something.
