To use NEC3 digital products, you will need to download and install a small plugin to your web browser. This will allow to unlock - 'unseal' - and view NEC3 digital contract documents. You will be prompted to download the Unsealer when you are buying digital products for the first time, but if you would like to test, download and install the plugin now.

The Unsealer software will run on nearly all PCs, but the basic requirements are:

• A Pentium PC running Windows 95 or above
• 10Mb of free disk space
• Internet access via a modem or corporate network (LAN)
• Internet Explorer 4 or above (recommended) or Netscape Communicator 4.x
• Adobe Acrobat Reader

If you don't already have Adobe Acrobat installed on your PC , it is available as a free download from the Adobe web site.
