I downloaded OS X 10.9.5 and when I attempt to load the program from OS X 10.7.5 I click on the install icon and nothing happens. How do I install the upgrade?

I downloaded OS X 10.9.5 and when I attempt to load the program from OS X 10.7.5 I click on the install icon and nothing happens. How do I install the upgrade? Can I upgrade from Lion to Mavericks? Here are my specs:
MacBook Pro
15 – Inch Core 2 Duo
Processor 2.33 GHz Intel Core 2 Duo
Memory 4 GB 667 MHZ DDR2 SDRAM
Graphics ATI Radeon X1600 256 MB
Serial Number W8****W0L
Software Mac OS X Lion 10.7.5 (11G63)
Is my system capable of running the new upgrades?

Sounds like you downloaded the OS X Mavericks 10.9.5 Update or Combo Update. Neither will work on a version of OS X prior to OS X Mavericks. Those are only used to update an existing install of OS X Mavericks. The Combo will update any version from 10.9.0 thru 10.9.4. The Update will only update version 10.9.4.
You need the full installer of OS X Mavericks from the App Store. However, the App Store no longer offers OS X Mavericks. Yosemite is the new FREE OS X.
