Installing 2013 sp1

I am willing to admit I am not the most computer savy guy out there but I know my way around.

I have had nothing but problems trying to download and install 2013 sp1.

I have had a varietyof automatic installer isues and had the manual download hang up at 90 plus percent a couple of times.

I finally got the main package to down load and now I have a folder with all the files in them but no setup file.

I need to get some work done!!!!!!!!

The only desktop icon I have is for SolidWirks explore.

How do I get the main program to setup manually?
