Opening Locklizard Safeguard protected PDC documents & files
- To open a PDC document you need a license from the Publisher – only they can issue this.
- The Publisher is the company who sent you the protected PDF document (PDC file), or is who you purchased the protected PDF document from.
- The Publisher will have sent you a license email so that you can open their protected PDF documents.
- Check your email to see if you received the license email from the Publisher. The license email contains usage instructions for opening protected PDF documents (PDC files) and your license information. It should look something like this:
- Before contacting the Publisher of the protected PDF document (.pdc file) for your license email, check your spam folder, as sometimes license emails get marked as spam due to the attached zip file.
- Some companies strip incoming email attachments, so if no license file is attached to the email and no link to the license file is provided, then you may have to ask the Publisher for your license file link.
- If you have not received your license email then contact the Publisher.
If you have received your license email then follow the instructions provided
- Download and install the Safeguard Secure PDF Viewer software.
- Double-click on the license file (.llv file) in your email application and select ‘Open It’ to activate your license.
Once you have registered your license you can then double-click on a .pdc file in Windows File Explorer (Windows), or on Mac, double click on a .pdc file. The protected PDF document (PDC file) will then open in the Viewer software as shown below.
