# Error Loading Extension

### Issue

When you try to start, update or re-install the Whatfix Player, the following error is displayed: ![image001 1.png](https://cdn.document360.io/a268766e-d74d-4619-9613-e2472f809ffb/Images/Documentation/image001%20%281%29.png?sv=2026-02-06&spr=https&st=2026-11-12T09%3A01%3A37Z&se=2026-11-12T10%3A01%3A37Z&sr=c&sp=r&sig=tlg0CwVrVlWz028Pf8DpLBGcktjm7ksz3X8DehAUrXc%3D)

### Probable Causes

The following are the various reasons the aforementioned error is displayed:

- A faulty installation of the Player took place.
- An older version of the Player app is already installed on your device and you try to install a different version or manually update it.
- The Player wasn't properly uninstalled and then re-installed.

### Suggested Solutions

- If you already have the Whatfix Player installed on your device, [update the Player directly from the Dashboard](/desktop/docs/how-can-i-check-the-version-of-whatfix-player-installed-by-my-organization).
- In case you still need to install the Player or if the issue persists, uninstall the version of Player already present on your computer and then re-install it. This ensures that there is no faulty installation or missing files in the Player's package. For more information, see [How to uninstall the Whatfix Desktop Player?](/desktop/docs/how-to-uninstall-the-whatfix-desktop-player)

Info

- Once the issue is resolved, any time you perform a push to production, any recent updates to the Player should get automatically pushed. For more information, see [Auto-update of Whatfix Desktop Player](/desktop/docs/autoupdateswhatfixdesktopplayer).
- Auto updates of the Player are not supported in [System level installation](/desktop/docs/system-level-installation-mass-deploy-player-using-msi-installer).
