What Each McAfee Error Code Means
- Error 201 — McAfee cannot connect to the update server
- Error 202 — Authentication failed during update (account issue)

How to Fix McAfee Error Codes 201–205
Step 1: Check Your Internet Connection
Open a browser and try to load mcafee.com. If the website doesn’t load, the issue is your internet connection — not McAfee. Restart your router and try again.
Step 2: Run McAfee Update Manually
- Open McAfee
- Click the gear icon > General Settings and Alerts
- Click Automatic Updates > Update Now
- If this also fails with an error code, proceed to Step 3
Step 3: Add McAfee to Firewall Exceptions
Your Windows Firewall or router firewall may be blocking McAfee’s connection to its update servers. Temporarily disable your firewall, run the McAfee update, then re-enable it.
Step 4: Clear McAfee Update Cache
- Close McAfee completely
- Navigate to C:\Program Files (x86)\McAfee
- Find and delete the UpdateCache folder
- Restart McAfee and try updating again
Step 5: Reinstall McAfee
If all else fails, use the MCPR tool to completely remove McAfee, restart, then reinstall fresh from mcafee.com. Or call +44-800-066-8910 for guided support.
