When you are using Microsoft Excel with activated Excel add-in, the add-in slows down the program. Opening Excel, working with it and closing it are slower while the add-in is running. When the add-in is deactivated Excel works faster and closes immediately.
Reproducing the Issue
Log on to the Excel Add-In.
- Starting, working with and closing Excel takes a long time.
The issue is occurring because of the latest security update from Microsoft.
The issue can be solved if you uninstall this security update, but this is just a work around. As a work around you can uninstall this security update:
- Go to Control panel.
- Go to Programs.
- Under Programs and Features, click on View Installed Updates.
- Search for Security update.
- Under Microsoft Windows uninstall the latest update.
