We will be introducing a Free DISAM Developer License early in 2015.
The license will expire each 120 days but can be easily renewed by simply doing another request for a link to download a refreshed package.
The free license is intended to make evaluation, development and testing easier but is not to be used for the distribution of any DISAM’d product.
A commercial license will be required for any distribution, whether free or for profit.
The commercial license will include complete DISAM source while the free evaluation/developer license will only include the DISAM library, tool binaries and required header files.
