You should have received an email from he Publisher telling you how to download / access it.
A PDC file is proprietary Locklizard protected PDF file.
The first time you purchase a PDC file from a Publisher you will receive an email with the information on how to install the Viewer and activate your license. Complete those two tasks and you will be able to open the PDC file. You must be connected to the Internet when activating your license and opening the PDC file (at least for the first time).
Licenses are tied to the machine they were registered on. Hardware changes and, rarely, even OS changes can invalidate your license activation. If this happens, contact the Publisher and ask for an additional activation for your license.
You are only licensed to view the PDC file on one computer unless you have been told otherwise. You must contact the Publisher to request an additional activation for your license.
No, once you have activated a license it cannot be used on any other machine. If you need to view a PDC file on more than one computer (home and work, for example), you must request an extra activation from the Publisher. If someone else needs to view the document, they need to have their own license, issued by the Publisher.
You must be connected when you activate your license and the first time you open a PDC file. On subsequent document opens, you may not have to have Internet connectivity – this depends on the document controls set by the Publisher.
Only if it has been allowed. The printout may have a personalized watermark with your name on it.
No. You cannot print to an Acrobat PDF driver or similar file driver. ALL ‘print to file’ (virtual) printers and some multi-function printers (printer/scanner/copier devices) are disallowed.
No, it is not possible to copy and paste content.
You can set the PDC to be shown full-screen, you can project it, and you can advance slide to slide similar to PowerPoint.
In some cases, documents will have been set to expire after a certain time period or after they have been opened a certain number of times. Any such limitation should have been explained by the Publisher up front when you purchased. You must contact the Publisher for more information regarding this, as we do not have access to their Administration Systems.
