I uploaded the ArcGIS on January 20. 2015. It worked just fine. Today, I had to do a "refresh" to my computer and all software installed was deleted. I bought the product through Webstore @ UIC. So, I went to the website to download again the product, but I couldn't finish the installation. I called 3 times customer support. Three different technical asistants tried unsuccessfully to help me. I need the administration part of the software to entry my key and make this software work on my computer, which I need for one of my classes, which are not free.
