WD Smartware No Longer Working

It stopped backing up about a month ago, without warning, and when I try to start it there is a message popup which shows and goes away in 1 second. I can’t read all of it but it says something about an invocation.

How do I fix this?

What Operating System do you use, Windows, Apple etc.?

If Windows try the Control Panel>Uninstall a Program scroll down to find Smartware. Click on it and at the top click on Repair. See if that solves your problem. See image below. Click on, tap or activate image to enlarge it.

Thanks for the reply.
I decided to try to uninstall and download the latest version.
This did run and I will see if it backs up tonight. I have it set for 12:00am.
