Subscription Renewal


Our software licenses include one year of free upgrades to the same product. This means that if you have purchased your license, for example, in March 2010, you may upgrade to the new versions of the same product released up to March, 2011 (both minor and major upgrades are free for one full year). Simply download the latest evaluation version of the product, install it, and enter your existing license key into it, that's all!

If, after you have installed the latest version, a message is displayed that you need to renew the upgrade subscription, you can order it below with 40% discount. When you purchase an updated license, you get a new year of free upgrades with it, as well!

Please select the product you would like to upgrade from (that is, the product that you have previously purchased) and enter your registration information for this product. Please refer to the original registration acknowledgement that we've sent you after you have purchased your license.

Professional Edition Upgrade


If you currently have the Standard Edition of WinLock or Maple, you can purchase the Professional edition at a discount.

ATTENTION: This is a restricted area for the licensed users only. We verify all registrations prior to issuing any upgrades. If you are not a licensed user of our software, click here for information on how to purchase a license.
