  +variable is set appropriately in <b>HackflightSimBuild.cs</b>.
  +
  +3. Make sure that the appropriate Python dll file file is in your
  +<b>C:\Windows\System32</b> folder. For example, if you're using Python3.6,
  +this will be <b>python36.dll</b> If it is not, you can copy it to there from the folder you specified in the
