 Visual SAT-Flare Tracker 3D - Download


The program doesn't require to be installed. Just unzip the archive and run the main executable file. The help will be available through the program menu.

The program will start with the OpenGL support active and by using a rendering mode that should work with all the graphic cards, however, the frame rate may result quite low in some cases. You can try to choose a better rendering mode for your system by executing the bath (.bat) files.
  • for Window users (Vista and Seven): the run-time error '339' may occur. In that case it may be necessary to unregister and register again the file 'COMCTL32.OCX'. From the folder where the program has been unzipped, execute the following commands as administrator:
    • regsvr32 /u comctl32.ocx
    • regsvr32 comctl32.ocx

In some cases, the problem can be fixed simply by selecting to run the program in "Windows XP compatibility" (right click on the executable file and select the option).
If the program still doesn't start, right click on the executable file and select 'Run as administrator'.

  • for Linux users: the program can work under wine after the necessary fonts are installed (font couri.ttf and pala.ttf). However, OpenGL may not work properly. If you need support, get in touch.
