The default filenames for the program's installer are HIARCS Chess Explorer.exe or Hiarcs732.exe etc. The most popular version of the program is 13.2. This software was originally developed by Applied Computer Concepts Ltd. I think that Hiracs uses the experience and (general) knowledge of the former X-Chess developer. The latest version of the program can be downloaded for PCs running Windows XP/7, 32-bit.

Conversely, if one distributes copies of the work without abiding by the terms of the GPL (for instance, by keeping the source code secret), he or she can be sued by the original author under copyright law. One is only required to adhere to the terms of the GPL if one wishes to exercise rights normally restricted by copyright law, such as redistribution. Because a GPL work is copyrighted, a licensee has no right to redistribute it, not even in modified form (barring fair use), except under the terms of the license. It earns its legal power from the use of copyright on software programs. When someone distributes a GPL'd work plus his/her own modifications, the requirements for distributing the whole work cannot be any greater than the requirements that are in the GPL. The distribution rights granted by the GPL for modified versions of the work are not unconditional.
