The Relm Pro Excel add-in updates itself most of the time without you doing anything. Occasionally — after a known fix lands or when the taskpane is stuck on an old build — you may need to force a refresh.
How updates normally happen
The taskpane's web bundle (the JavaScript that renders the UI) lives at excel-plugin.relm.ai. Excel fetches it fresh whenever you open the taskpane, with normal HTTP caching. So most updates appear within minutes of release without any user action.
The manifest (the XML that defines ribbon buttons and points to the bundle) updates differently:
- AppSource — automatic, Microsoft pushes it.
- Sideloaded — manual; you get the updated file from Relm support and replace the old one.
Force-reload on Windows / Mac
Quickest path:
- Close the Excel taskpane. Click the X on the taskpane.
- Re-open the taskpane. Excel fetches the latest bundle.
If that doesn't pick up the change:
- Close all Excel windows.
- Re-open Excel.
- Open the taskpane.
If that still doesn't:
- Clear the Excel web cache. Microsoft has a documented procedure per OS.
- Restart Excel and open the taskpane.
Force-reload on Excel for the web
- Hard-refresh the browser tab (Cmd/Ctrl + Shift + R).
- The taskpane's web view picks up the new bundle.
Verifying the version
The taskpane doesn't show a version number. If you're not sure you're on the latest build, reload using the steps above; if the problem continues, contact support.
When updating doesn't fix the issue
If you're stuck on an older build despite reloads, the issue is usually:
- Corporate proxy caching. Your IT may have aggressive caching that pins old versions of the bundle. Ask them to bypass caching for
excel-plugin.relm.ai. - Sideloaded manifest is stale. The manifest itself may be old. Ask Relm support for the current file and replace it.
- Excel client is too old. Office Add-ins require relatively-recent Excel builds. Update Office to the latest stable.
Manifest updates
Most updates are bundle-only and don't need manifest changes. When the manifest changes (new ribbon button, new icon, new permissions):
- AppSource users: automatic.
- Sideloaded users: replace the manifest with the updated file from support, then restart Excel.
We announce manifest changes in release notes when they happen.
