This error, identified by the error code Error Code 6002, can impede your system’s performance, and here’s how you can fix it.

Identifying the Problem

Error Code 6002 arises when the user attempts to access an encrypted file but doesn’t possess the necessary decryption rights. The error message may appear in different scenarios, such as:

If you encrypted the file and have the key, use it to decrypt the file and resolve the error.

2. Restore File Ownership

Right-click the encrypted file, select “Properties” > “Security” tab > “Advanced” button. In the “Owner” tab, click “Edit” and assign ownership to yourself.

3. Disable Antivirus Encryption

Some antivirus programs automatically encrypt files. Disable encryption by configuring the antivirus software settings.

4. Use a Third-Party Decryption Tool

If the above methods fail, try using a third-party file decryption tool to recover access to the encrypted file.

Advanced Troubleshooting

1. Check File System Errors

Run the “chkdsk /f /r” command in Command Prompt (Admin) to scan and repair file system errors that might have caused the encryption issue.

2. Revert System to a Restore Point

If the error started occurring recently, perform a system restore to revert your system to a point before the error appeared.

3. Reinstall Operating System

As a last resort, you can reinstall the operating system to eliminate any underlying issues causing the encryption problem.
