2. Your web browser may show you a progress bar of some kind at the top or bottom of your browser window. It may take a few minutes depending on your internet connection speed.
   
   
3. In your "Downloads" folder look for the file: "QuickPhasePro_5.x.xx_Setup.exe" (your file will have the "x" replaced with numbers depending on the version). Double click the file to begin the installation process.

This version still works great and is available for a lower price but it is no longer being updated. Version 4 is very similar to version 5, EXCEPT it does not have planetary data and the new graphs. It can be installed and run alongside version 5 without any conflict so you can try both if you wish.
