Dena,
You've made this difficult to answer. Esteel has given you clear instructions already. I'll make another attempt....
Here are step-by-step instructions for Windows with 7zip installed:
1. Download Nexuiz-242.zip to my desktop
2. Go to my desktop (Windows key + M)
3. (with 7-zip installed) Right click on the nexuiz zip file and "Extract Here"
4. There should be a new folder on the desktop called "Nexuiz".
5. Double click the Nexuiz folder to open it.
6. Double click the Nexuiz.exe file to launch the program.
7. Smile and play Nexuiz.
If, after folliowing the above steps, Nexuiz does not run or you get an error message, then you need to provide a screenshot of the error message OR type out the message. If you don't do this, then nobody here can help you fix the error. You asked us to be PRECISE in our response, so I'm asking you to be PRECISE in describing the problem.
