cannot run SL?

Hi im new to all this cannot seem to run SL keeps saying about running in full screen or different not able to run 24bit needs 32. so how do i over come this?????? pls help.

You are trying to run the game when your computer is set to use 24 bit color. SL needs your computer set to 32 bit colors to run.

Right click on your desktop and select properties. Click the settings tab on the top right of the window. There should be a drop-down menu over a color bar that says "Colors." Click on it, select "True Color (32 Bit)," and hit the "Apply" button, then your monitor may flicker as it applies the new settings. Hit "Yes" if a window pops up asking you to keep settings, then hit "Okay."

If you cannot select 32 bit, sell your computer to a museum for a wad of cash and buy a new one, or update your drivers, or buy a video card.
