Overview
When using a Runner you may start seeing failures associated with the following error in your Runner's logs:
level=warning msg="could not update launch-agent to new version: error checking agent for os=\"windows\" arch=\"amd64\": Get \"https://runner.circleci.com/api/v2/launch-agent/download
This error is easily addressed!
Upgrade from Launch Agent to Machine Runner
This error is stemming from the fact that your runner implementation still uses the deprecated launch agent, and not the supported Machine Runner 3.0. To resolve the issue, you must upgrade to Machine Runner 3.0
You can find instructions on how to migrate from launch agent to Machine Runner 3.0 here on our documentation site:
