The most common cause is a missing or damaged Swift runtime, often after a Windows update or system change. Sometimes, your antivirus software or a damaged user profile can also cause this problem. Before we move on to the troubleshooting steps, it’s a good idea to restart your computer. Restarting will refresh all services and clear out any temporary glitches in the system’s memory that might be stopping Arc from launching.
1. Reset or Repair Arc
This method worked for me and is usually a great starting point. Resetting Arc clears its application data, including saved login info and recently used data. Repairing the Arc browser will try to fix any damaged files that may be causing the issue.
2. Close Arc from the Task Manager
Sometimes, multiple instances of Arc may be running in the background, which can stop it from launching properly. Closing all Arc processes from the Task Manager usually solves this problem.
3. Run Arc as an Administrator
Running Arc as an administrator gives it all the permissions it needs to work properly. Sometimes, programs can’t start because they don’t have permission to access certain files they need.
4. Reinstall Arc Browser
If none of the previous solutions work, reinstalling Arc is a good next step. This will replace any damaged files that could be causing the browser not to launch. If reinstalling doesn’t fix the problem and Arc still refuses to launch, you should report the issue to Arc browser support. Their team can take a closer look and provide more detailed help for your specific situation.
