Can't download El Capitan from Appstore. Constant Spinning Wheel
This is not really a true answer. But eventually after attempting to download El Capitan several times, it all of a sudden began to download. Once it downloaded I put the OS on a flash drive, booted off of it, wiped the drive, and performed a clean install. After that the system has been operating flawlessly. I guess when they gave it to me, something must have gone wrong during the install that got overlooked? not sure. 

To be honest I do not know what software I was trying to install first when this all began. But it was something simple. This happened to me on every installation of any product that involved using an installation package. i.e. Adobe flash, Teamviewer, my logitech mouse drivers. It was happening on everything I tried to install. I just don't remember the first thing it was I tried to install.

Anyways now it's all up and running after the clean install, and performs flawlessly. Hopefully this doesn't occur to me again. 

Thanks,
