Step 3.  Click to proceed checkout

Step 4. Input your name and User ID (these are optional)

Step 8.  Click

Step 9. Click

NOTE!! After you click , the transaction should be completed, as we will show you in the next step. However, if something is wrong with your credit card, error might occur here, like the screenshot below. You need to check the error message and contact your card issuer about this error. Please note that because we are selling virtual goods (software license is virtual without physical goods), some credit card issuers might deny this type of transaction. Please communicate with your credit card issuer to permit this type of transaction on your card.

Step 10. Keep the license code and read the “System Maintenance Guide” before installation

Step 11. Bring up License Manager

To bring up license manager, right-click on the NVR organizer. In this alternative, however, you must note following:

• You must have administrative privilege. As running license manager requires administrative access to your computer.
• On systems like Windows Vista or Windows 7, where administrative privilege is often not given in default scenario, you will need right-click NVR organizer and select "Run as administrator" to let the program gain administrative access.
• The NVR engine service must NOT be also running. That is: only one of NVR engine and License Manager can be running at the same time. They are, sort of, exclusive to each other. If you try to start NVR engine service while License Manager is running, it will cause the NVR service license check to fail.

• Windows 7 and Hidden Tray Icon

In Windows 7, tray icon is hidden by default. You have to click the white triangle to access hidden icons.

• To make the hidden icon always visible, click “Customize...” and set the icon to “Show icon and notifications”.

Step 12. License Manager - Install package online

The fastest and most convenient way to install package is through "Install package online" option. You will need unrestricted access to the Internet to use this option. Please note however, using this option means you will need Internet even in normal operation, as License Manager will check in the background periodically for license validation. (see Concepts.)

After clicking "Next", following screen will appear. You need to enter purchase code, package, and desired quantity. Please note the desired quantity must not exceed the remaining purchased quantity. If you check the "Commit to current computer" box, this will became an offline license (unless the licensing terms doesn't allow that). You can always convert an online license to an offline one later.
