You'll need a program to extract the setup file from the zip. You can use Winzip, which is a free program for extracting zip files:
http://www.winzip.com1) Right-click on the zip file and select "Winzip > Extract to..."
2) Extract the setup file from the zip to a temp directory - one that you can easily remember and navigate to
3) Find the setup file - it'll be named the same as the zip, but have an "exe" extention and appears with a different icon
4) Double-click the setup file and follow the on-screen instructions
Once the setup has finished, it's simply a matter of starting Train Simulator and selecting the geeps from the locomotive pull down menu. If you want to create new consists, use the ConBuilder program available from our
Downloads pageLet me know how it works out.

Cheers!
