@Reporter: Could you check by uninstalling current build and installing latest build. You can download build from https://www.chromium.org/getting-involved/dev-channel.

Thanks!

Try the below scenarios
=======================

Scenario 1:

1. Close all the chrome background process(if any)running in the background.
2. Relaunch browser and try to update.

Scenario 2
===========
1. Create a new browser user profile
2. Clear cache and cookies
3. chrome://settings- Reset Chrome browser settings
4. Update

If both the above scenarios doesn't work, uninstall and reinstall chrome(IMPORTANT: Make sure to backup your USER DATA folder) otherwise you will loose all the saved browser data.

0x80080005 means that the Google Update service, which is the underlying client infrastructure to handle the Chrome updates, could not start (the specific error is CO_E_SERVER_EXEC_FAILURE). There are many possible causes for this, including interference from anti-virus or similar software. You can try downloading and running the Chrome installer from https://www.google.com/chrome without uninstalling Chrome. This should not touch your user data. It may allow Google Update to repair itself.

As there isn't any Feedback from reporter from long time, closing this issue and marking it as Won't Fix.

@Reporter: Requesting you to file/raise a new issue if the issue is seen again.

Thanks!
