[The newly downloaded software won't run]

I need your help. I downloaded a software for displaying the data that I collect using a magnetometer. The software is developed by the manufacturer. I was able to successfully install it, but, when I try to extract the file and execute the program, it doesn't work. I tried re-installing, however, nothing changed. It doesn't show an error msg.This is the software I installed,

I am using Windows 8 OS. Could it be that it doesn't run on 8? what do you think ? I need your suggestions. 

 

Thanks.

I usually tether using my smartphone as a hotspot. I hadn't noticed any difference in speed while connecting via USB and Wi-Fi.
