If you already own a registration key purchased from eSellerate or Paddle for an earlier release of UI Browser 2, you can continue to use it to run this version 2.9.0.

If you do not own an existing eSellerate or Paddle key, you must purchase a key from Paddle, our new ecommerce provider, to run version 2.9.0 after the trial period expires. A Paddle key can only be used to run release 2.8.2 or later of UI Browser 2.

Purchase a registration key from Paddle to unlock the trial version if you don't already own an existing eSellerate or Paddle key. Go to our Online Store using any commonly available Mac web browser. UI Browser is $55.00 US. If you have a discount coupon, you can enter the coupon number in the order form. Volume discounts are no longer available. When you receive your key from Paddle, launch UI Browser and choose UI Browser > Registration > Enter Key. Enter your email address and the key exactly as they were provided, and activate UI Browser when asked.

If you prefer to purchase a Paddle key within UI Browser while it is running, choose UI Browser > Registration > Purchase Key while you are connected to the Internet. Follow the instructions in the Paddle UI Browser purchase dialog, and activate UI Browser when asked.

Be sure to save your registration information in case you ever need to reinstall UI Browser. Individuals who have purchased this version of UI Browser are licensed to use it on their home computer, their office computer, and their laptop. If you need to deactivate UI Browser on one of them to install it on another computer, choose UI Browser > Registration > Deactivate.
