Canot install iTunes in Windows 7

I downloaded the latest iTunes version directly from Apple. When I double click on iTunesSetup.exe file, the mouse pointer goes busy for a short time, and then nothing else happens.I can see the iTunesSetup.exe process show up in the Task Manager for one second, before it quietly vanishes again.
How can I install iTunes software in windows 7?

You should delete every iTune folder under Users/Local, LocalLow, and Roaming, and Programs Files, and clearing out all Temp files.

Now you can start to install iTunes in windows 7.
