Check out Add/Remove programs to make sure that IIS Express is insatlled. Also, you can check out \program files\iis express\ and make sure that IISExpress.exe is there.
Hope this helps.

may I know what OS you have on your system? Are you using Windows Server 2008 R2 in this case? Windows Server 2008 R2 has come with IIS 7.5 and more likely, you will have this kind of problems

Sorry your having more issues.
http://learn.iis.net/page.aspx/479/iis-70-features-and-vista-editions/ Features guide
You likely need to use Windows Features Turn on and Enable Section of the Control Panel.
Guide for installation for Vista with Pictures
use the Figures 6-8 for Features and expect that a restart will be required to finish the Configuration.
The Web Platform may be having problems with automating the IIS Features portion so you may need to do it manually.
