"after it installs" - where did it install to?  Are you distinguishing between the downloaded installer
and the installed Mathematica?

Quick suggestion:  http://support.wolfram.com/kb/3274 
Did the installation go normally?  See  http://support.wolfram.com/kb/10650 

Suggestions will have to be operating-system dependent.

On Windows:
- Look in Start menu - All Programs for Wolfram Mathematica. Can you launch it from there?
- Does holding down the SHIFT and CONTROL keys as you try to start Mathematica make a difference?
- The Mathematica Kernel should be in
       Start menu - All Programs - Wolfram Mathematica - Mathematica Kernel.
   Can you start that?

On Macintosh:
- Was there a problem unpacking the downloaded .dmg file?
- In the Applications folder, does Mathematica.app show up?
- Try the Mathematica Kernel:
  - Open the Applications folder,
  - hold down the Control key,
  - click once on the Mathematica application (.app) and then
  - select "Show Package Contents".
  In the folder that opens,
  - open the Contents folder, then
  - the MacOS folder. 
  Double-click the MathKernel icon and a stand-alone kernel will launch.


Linux:
- In a terminal window, type and run
    rehash
and then
    math
What happens?

I had a similar problem running Maple under Windows 8. Check in task manager whether or not Mathematica is actually running. In my case, Maple was running but the GUI was not displaying. I went through a lot of diagnostics and pinned the problem on the Base Filtering Engine service, but it could have been any conflicting service or program. By working off-line, I could turn Base Filtering off in the Task Manager and the Gui showed up. When I updated to Windows 8.1, the problem was resolved. It was suggested that the Base Filtering module was corrupted. Maybe.

Anyway, these are some insights on a similar problem and its resolution.

Good luck.
