Download the Tacsail Trial Version V3.1 :  Tacsail Installer Package  or the Manual only. All features of the PRO version are enabled in the trial version with some limitations. Previous versions, if not required anymore, should be uninstalled before installing V3.1.  If older versions than V3.1 are removed after having installed this V3.1 version then the V3.1 installation will have to be repeated.

To enjoy of all features (Gribviewer and MapLib tool), the program compatibility settings should be set to 'Run as administrator'.

Do not remove any of the demo files which come with the program in the different folders, otherwise the program will attempt to repair the oiginal installation by replacing them in their respective folders. While installing on newer systems (W7 and up), Windows will issue a warning. You can safely ignore this and continue. Secondly, unless UAC (User Account Control) is set to the level "Never notify", each time when you start Tacsail the Windows OS will issue a similar warning before you can start up the program.
