install from administrative image

Why is it so difficult to install from an administative image? Where is the user guide for installing from an administrative image? I've created an image but nothing in the SOLIDWORKS 2016 x64 SP02 folder is working to install on an individual computer. This should really not be that difficult. All i wanted to do was update from SP01 to SP02 and this is taking me way too long. I expect a simple setup.exe that launches the installer on any computer i want to install it on for what I paid for this software.
