14 Jul 2011 News for NTIA/ITS HF Propagation Models (WINDOWS version) 14 Jul 2011 1. The only change in this version is a new SALFLIBC.DLL . A user was installing the software on a pc ALIX1D mini with XP operating system. When he tried to execute VOACAP, he got: Fault code with Pointwin.exe error gives no installation(0xc000001d). I downloaded a new version of SALFLIB.DLL from the compiler company, and that solved his problem. Let me know if this causes other problems.
