Version 7 installs files in two locations.
The default location is C:\Program Files (x86)\PowerMation\Poles 'n' Wires. This is where the program files/module are put. You will probably not have write access to this location.
This is C:\ProgramData\PowerMation\PolesnWires and is where data and licence files are put. By default Windows hides this directory so you may not see it without some effort. There is a shortcut to this directory under the Windows Start> Programs> PowerMation> Poles 'n' Wires menu.
