The demo download is an executable file. Save it to your Desktop and click on the icon labeled MW3 Demo.exe/TW3 Demo.exe/PW3 Demo.exe. The demo will install and leave a shortcut on your desktop. The IST Demos runs on Windows XP, Vista, 7, 8 or 10.
File not downloading? It could be that your security settings or anti-virus software are blocking it because it contains an .exe file. Try right clicking on the link and selecting "Save As". It will begin the download. Next to the download it may say "blocked" or something similar. Click on the up arrow to the right to change it to "accept" to allow the file to download.
If you still can't get it to download, contact [email protected] and we'll help you.
NOTE: If you are unable to download one of the demo packages, please call 800-835-2611 to ask for a CD or USB copy to be mailed to you.
