I'm sorry to hear you're having problems. As Kenneth said, you first need to download the .Net Framework, but you need to have a specific version of it as well; .Net 3.5 SP1. That is the latest available version, and you can download it from
Here.Once that is installed, download the game from
Here. Once that file is downloaded, you will need to unzip it with an archiving program such as
Winzip (Free Trial Only) or
Winrar (Which is free but is much less user-friendly)
Use whatever program you choose to unzip the files into a folder of your choice. Once that is complete, open the folder and locate the file called SupremacyClient.exe, then load it up.
If you have problems let us know. Oh, and what version of Windows do you have? There are some other things you need to do to get it working if you have Windows 7.
