Which folder to choose for installation?

I just downloaded the Dell 2135cn ZIP file for 64-bit Windows 7. After unzipping the file, I am left with three installation folders labeled with ABE, SBM, and SSW. There is no README file, and I have no idea which folder to choose for installing the application and drivers. Can anyone offer me some insight? Thank you.

UPDATE: Never mind. Figured it out by running each installer and reading the title bar. Too bad a README file did not explain this.
