If Microsoft Windows report that "it cannot open the file" then you have neither WinZip nor Windows Zip Explorer installed. In this case, you need to download the Winzip Evaluation version which you can download by clicking here and selecting "Download Evaluation". Follow the same steps as listed above (save to an easy-to-remember location, double-click the downloaded program) and then install Winzip Evaluation by following the prompts. When Winzip asks you what interface to use select "Classic".

If you have the WinZip evaluation version, then after clicking the "dtf.zip" Zip file you have saved earlier (on your desktop for instance), you need to click the "I Agree" button and then click on the "Extract" button on the top button bar. You'll then be asked where you want to save the documents on your computer. Again choose a location that is easy to remember, like for instance your desktop.

If you have Microsoft Windows Zip Explorer (comes default with Microsoft Windows XP) you can simply double-click the "dtf.zip" Zip file you have saved earlier (on your desktop for instance), and then select "Extract all files" under "Folder Tasks" in the top left of the window. Follow the wizard to save the extracted files. Choose a location that is easy to remember, like for instance your desktop.

Finally go to your desktop (if this is where you extracted the files to) and double-click the file named "Defend the Faith.exe"

Once you have saved the executable (.exe) file to your computer, you need to go find it (for instance on your desktop), and double-click the file named "dtf.exe"
