The Installation of Norton Ghost v15 is Stucks on Win7!

I have Windows 7 Ultimate on my computer, and allways when I install the Norton Ghost v15, the Installation Program stucks after it finishes the installation and it isn't process to the End Dialog Box.

Only what can I see it is a Blank Bar on the Installation Dialog Box.

I open the Manager Tasks and I see it's Lsetup.exe, LuCheck.exe, LUSetup.exe, setup.exe,msiexec.exe that belong to the installation.

Why does it allways jam at this point? Please help me!
