Operating systems find command line programs using a special environmental variable called the PATH variable.
Iguana X uses the PATH variable to locate Git and ssh.
In addition if Iguana X can find Git on windows, but not the ssh tools - then it looks for these tools in the place that the Git windows installation has them.
What problems can this cause?
Environment variables are only read by a program when the program starts. So if you alter the PATH variable after Iguana X has started, it will be necessary to restart Iguana X in order to pick up the PATH setting.
We try to make it easy to diagnose these problems by showing the system path in the Git set up screen.
