Symptoms of Facebook error 502

1. Error 502 appears and crashes the active program window.

2. Your PC frequently crashes with Error 502 when running the same program.

3. Facebook Error Code 502 is displayed.

4. Windows runs sluggishly and responds slowly to mouse or keyboard input.

5. Your computer periodically freezes for a few seconds at a time.

Causes of Facebook error 502

1. Corrupt download or incomplete installation of Facebook software.

2. Corruption in Windows registry from a recent Facebook-related software change (install or uninstall).

3. Virus or malware infection that has corrupted Windows system files or Facebook-related program files.

4. Another program maliciously or mistakenly deleted Facebook-related files.

Solution

Step 1: Repair Registry Entries Associated with Error 502

Manually editing the Windows registry to remove invalid Error 502 keys is not recommended unless you are PC service professional. Incorrectly editing your registry can stop your PC from functioning and create irreversible damage to your operating system.

Step 2: Conduct a Full Malware Scan of Your PC

There is a chance that your 502 error could be related to a malware infection on your PC.

Step 3: Clean Out Your System Junk With Disk Cleanup (cleanmgr)

Over time, your computer accumulates junk files from normal web surfing and computer use.

Step 4: Update Your PC Device Drivers

502 errors can be related to corrupt or outdated device drivers. Drivers can work one day, and suddenly stop working the next day, for a variety of reasons.

Step 5: Utilize Windows System Restore to “Undo” Recent System Changes

This can potentially help you avoid hours of troubleshooting headaches associated with 502 errors.

Step 6: Uninstall and Reinstall the Facebook Program Associated with Error 502

If your 502 error is related to a specific program, reinstalling Facebook-related software could be the answer.

Step 7: Run Windows System File Checker (“sfc /scannow”)

Step 8: Install All Available Windows Updates

Step 9: Perform a Clean Installation of Windows
