ParkTracer will run on Windows Vista and Windows 7, but here is something that you should bear in mind:
Installing ParkTracer
After you have downloaded the installation program (and saved it somewhere you can find it,
preferably on your desktop), right click on the file and select "Run as administrator" to install ParkTracer. ParkTracer will be
installed by default in the folder C:\ParkTracer. If you are installing ParkTracer for the first time,
please do not change the default folder.
