Brief Overview:

ProEssentials is sold as a product per developer.  If multiple developers will be developing with ProEssentials, requesting technical support, requiring documentation, references, header files, import libraries, and other compilation materials, then one copy of ProEssentials is needed per developer.  

Placing ProEssentials on a build machine or personal laptop is allowed as the product is licensed per developer.

For client-side distribution, ProEssentials is Royalty Free when distributed with your client side EXEs.

For server-side distribution, purchasing ProEssentials allows distribution onto five Production Servers and is not Royalty Free and requires an inexpensive run time Limited Distribution License (LDL) if distributing onto more than five IIS servers.  For most customers, no additional licenses are necessary. If a customer buys multiple copies of ProEssentials for multiple developers, they are allowed the additional server distribution rights.  Contact Gigasoft if you will be distributing to more than 5 IIS servers. 

Our product license is located in the install folder, filename V10LIC.TXT
