Remove/Update Excel Add-In Sideloaded via Shared Catalog

Question

I am developing/testing an Excel Add-In. I added it to the desktop version using the "shared folder catalog" process outlined here:

https://docs.microsoft.com/en-us/office/dev/add-ins/testing/create-a-network-shared-folder-catalog-for-task-pane-and-content-add-ins

I updated the manifest XML for new ribbon commands, but Excel is not updating. I am unable to update/remove/reinstall an add-in installed from the "Shared Folder". I tried removing the add-in catalog and re-adding it in Trust Center Settings, but that did not work.

Answer 1

It is caching your manifest. Try bumping the version number in the manifest. This will alter Excel that it's cached manifest is no longer valid.

If bumping the version doesn't trigger the update, you can manually clear your cache by deleting the contents of %LOCALAPPDATA%\Microsoft\Office\16.0\Wef\. For non-Windows environments, see Testing & Troubleshooting in the Office.js documentation.

Answer 2

The solution to this was pressing the Refresh button in the top-right corner of the 'Office Add-Ins' dialog.
