Before you buy, please follow the link above to install and test a free trial copy.  You have to do this even if you are buying the software as a gift.  This is the only way to insure that the software will run on your computer.  Because of the nature of the product refunds are not available, so it is important to verify that the software runs on your computer, before you buy it.  Within the program, you can create an online account for free.  If you buy the software I will set your account status to enable the software to save models and XAML code.

To use Calder, your computer must be able to be connected to the internet at least part of the time for periodic validation of the software.  There are no CDs or other media distributed with the product.  The trial version you install is the actual software and all features are enabled once an entry is made in the user database.  To validate your software, you will periodically have to login with your username and password.  You only have to do this every few days, not every time you use the software. 

You can create an account within the software by using the Validate command on the Help menu.  You should create a username and password before you send your payment.  When you send your payment, include a note with your exact username so I can upgrade your user status and enable all your features.

You can always download the latest Calder 4D updates for free at any time.  Your entry in the Calder database is what keeps  your user status active.  Please do not share your username and password with others - an account is for one person only. 
If you share your username and password, your account can be revoked.

PayPal is the the safest and easiest way to pay online.  You don't have to have a PayPal account -- all you need is a credit card.  I will never see your credit card number - it is only seen by the Paypal web site which is absolutely secure.

When your payment arrives, I will email you as soon as I have updated your user account information to enable all your software features.
