Overview
When updating from an older version of Office Timeline to the latest build, the installation may fail to complete.
Most update issues are related to differences between older VSTO-based versions and the current NetOffice-based version, or to PowerPoint add-in settings.
Symptoms
After updating to the latest version of Office Timeline, you may experience one of the following:
Office Timeline is no longer visible in PowerPoint
You receive an error related to an older VSTO-based installer
You receive an Error 1001 message when uninstalling or upgrading
Solution
If Office Timeline is not visible in PowerPoint after updating:
- Restart PowerPoint
- Go to File → Options → Add-ins
- Select COM Add-ins → Go
- Ensure "Office Timeline" is enabled
If you receive a Visual Studio Tools for Office (VSTO) error during installation, you are likely using an older installer. Download and run the latest version of Office Timeline from: https://www.officetimeline.com/updates.
If you receive Error 1001, the previous version may not have been removed correctly. Uninstall the older version of Office Timeline, then install the latest build. See how here.
