Don't know how to get an icon that will open the program [Closed]

I've just downloaded openoffice but have no idea what to do now. Had it on computer but computer crashed, now I have to start over & don't have a how-to person to guide me. I used to have an icon for openoffice but don't know how to get one back, etc.
Stuck dead in water. The document files I need are still here but I can't open them!
