Troubleshooting GraphicSchedule COM Add-in Errors

Symptoms

When you run Excel, the GraphicSchedule add-in ribbon tab is missing, and you see an error that resembles:
“Load Behavior: Not loaded. A runtime error occurred during the loading of the COM Add-in.”

Resolution

This error typically indicates that a component required to run the add-in is missing. The GraphicSchedule add-in requires Microsoft .NET Framework 4.8.1. You may download the missing component here:

Verify that “Load Behavior” says “Load at Startup”:
