Make sure you have your Adobe account credentials or software license keys available, in case you need to switch or upgrade your Acrobat installation.
Verify Your Acrobat Edition and Upgrade to Pro
Check your current installed edition, as the Remove Hidden Information feature is exclusive to Acrobat Pro.
Advanced redaction tools, including the Remove Hidden Information feature, are only included in the Pro version of Adobe Acrobat. If these tools were available before your computer was reformatted, you were likely running Acrobat Pro previously.
Launch the Adobe Acrobat application currently installed on your computer.
Click on 'Help' in the top menu bar, then select 'About Acrobat' from the dropdown list.
Look at the splash screen to see if your software is listed as 'Acrobat Standard' or 'Acrobat Pro'.
If the edition is 'Standard', you must either locate your original Acrobat Pro installation media and license key to reinstall the correct version, or purchase an upgrade to the Pro edition to regain access to the hidden information removal tools.
