08 Dec 2009 News for NTIA/ITS HF Propagation Models (WINDOWS version) 08 Dec 2009 1. A change was made in the installation to allow HAMCAP installations to know where the software was installed. The uninstall information can be found in the registry under: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ uninstall\{1B328085-F1A5-4AB8-8986-0103C5800216} The strange string: {1B328085-F1A5-4AB8-8986-0103C5800216} is called the GUID (Globally Unique IDentifier). It is generated by the Tarma installer and it has been set so it will never change.
