All software is available for download from this web-site. Note that only trial versions (i.e. the versions that have functional or temporal limitations) can be downloaded.
In order to get the fully-functional version of a program and remove restrictions and limitations you need to register the program, i.e. to purchase the license to use it.
The physical confirmation of your purchase is the receiving of the registration code for the program and license certificate (not for all cases). When the code is entered, all restrictions will be removed and you will get the fully-functional program.
Therefore, the primary method of the program delivery is Electronic Software Delivery (ESD), i.e. the receipt of the registration code/license certificate by email after the order will be successfully processed.
