That is probably the contents of the unzipped folder you see. The next step would be to double-click on the one that is:
- labelled "setup"
- unlike the others, is a icon that indicates it is the program
- the one that is described as "an application" unlike the others
- one that looks like a "setup or installwizard"
One of those files is the one we call "an executable" file. That one is the one that "runs" the program. It has a "file extension" .exe. The rest of 'em, like the "read me" have file extentions like .txt or .dll and they sorta help in different ways to make the software program work in Windows. It varys so much from one downloaded program to another that there is no set way to decide, exactly. If I knew which Windows type system you have I could help a little more perhaps, miriumdances
Once you open (double-click) the right one, the InstallWizard takes over and you are off and runnin'. Let us know how we can help you more.
