Registering DU Meter

The Register DU Meter window turns your copy of DU Meter from a trial into a licensed one. Open it with Register in the pop-up menu, which is there until DU Meter is registered.

Buy DU Meter

Opens the DU Meter purchase page in your browser. Your user name and serial number arrive by e-mail, usually within minutes. If you have a license for an earlier version of DU Meter, the window offers Upgrade DU Meter instead, which opens the upgrade page: see What is DU Meter upgrade policy and how do I upgrade? for what an upgrade costs.

If the page does not open, the window shows its address, which is also on your clipboard: paste it into your browser.

Enter your serial number

Enter the user name and the serial number exactly as your order confirmation e-mail shows them, and click Register. Copying both from the e-mail is the surest way: see How to copy and paste your serial number.

If the window says the two do not match, or that the serial number is for an earlier version of DU Meter, Registration problems explains what to do. Lost your serial number? opens the page where you can have it sent to you again.
