After these steps, you should have a working FFGo. You can run it by double-clicking on either <tt>ffgo.exe</tt> or <tt>ffgo-noconsole.exe</tt> in a directory such as <tt>C:\Python</tt><i>XY</i><tt>\Scripts</tt>, where <tt><i>XY</i></tt> corresponds to the Python version that was used in the <code>pip install FFGo ...</code> command. These two executables do the same, except <tt>ffgo.exe</tt> opens a Windows terminal (“console”) containing all FFGo messages, while <tt>ffgo-noconsole.exe</tt> doesn't. You can safely use the latter most of the time. Should FFGo refuse to start for some reason, running <tt>ffgo.exe</tt> and examining/reporting the printed messages would certainly be helpful. You may want to create shortcuts for these files by right-clicking on the <tt>.exe</tt> file of your choice, choosing <i>Create Shortcut</i> and dragging the newly-created shortcut to the final, desired place (e.g., your desktop). | After these steps, you should have a working FFGo.

{{tip|If you wish, you can also run FFGo from a Command Prompt; here is how. | |||
The instructions given | <p> | ||
First, [[Command_line#Windows|open a Command Prompt]], then: | |||
</p> | |||
<ul> | |||
<li> | |||
if you chose to add <tt>python.exe</tt> to the PATH in the Python | |||
installer as hinted above, just type <code>ffgo</code>; | |||
</li> | |||
<li> | |||
otherwise: | |||
<ul> | |||
<li> | |||
either run FFGo directly using a full path to one of its | |||
executables<ref name="Windows-allows-omitting-.exe-extension">As | |||
shown in the command, you may omit the <tt>.exe</tt> extension from | |||
the executable name.</ref>, such as: | |||
<pre>C:\PythonXY\Scripts\ffgo</pre> | |||
</li> | |||
<li> | |||
or change to the containing directory, then run the executable you | |||
want, as in: | |||
<pre>cd C:\PythonXY\Scripts | |||
ffgo</pre> | |||
</li> | |||
</ul> | |||
</li> | |||
</ul>}} | |||
The instructions given above install all dependencies of FFGo, except one optional dependency: the [http://geographiclib.sourceforge.net/html/MagneticField.1.html MagneticField] executable from [http://geographiclib.sourceforge.net/ GeographicLib] (see [[FFGo#A word about GeographicLib|below]]). To have a complete installation, that is able to show the magnetic variation at each airport and magnetic headings for runways, routes, etc., you need to do this in addition: | |||
# Go to [http://geographiclib.sourceforge.net/html/install.html#binaryinst GeographicLib's installation page] and run the appropriate installer for your system. This will install the <tt>MagneticField.exe</tt> executable on your computer. Take note of the folder it is installed to, because you'll have to tell the full path of this program to FFGo, unless you let the GeographicLib installer modify your <tt>PATH</tt> environment variable. | # Go to [http://geographiclib.sourceforge.net/html/install.html#binaryinst GeographicLib's installation page] and run the appropriate installer for your system.

# <tt>MagneticField.exe</tt> needs one or more datasets to be installed, otherwise it can't work properly. To get such a dataset, go to [http://geographiclib.sourceforge.net/html/magnetic.html GeographicLib's page for magnetic models] and install the magnetic model data file(s) of your choice. <tt>wmm2015</tt> should be fine until 2020. You may also install the <tt>emm2015</tt> dataset, however I can't say whether this will bring any visible change for typical aviation usage. | # <tt>MagneticField.exe</tt> needs one or more datasets to be installed, otherwise it can't work properly.
