I have CDR software GPRS.
On the download page, there is a paragraph where developers explain how to acquire an activation code. Basically, you have to posses a certain device to quality. Here is the text from their website:
When you download and install a product it may require a new authorization code for activation. If you have a valid SW subscription contract, you will have received a new authorization code automatically before the product was released. Otherwise, please contact Netcare International Ltd. before downloading the newest version of your SW product. We will instantly send you a new authorization code.
