Configure Win ISI Desktop Icon in Windows 7

I have received lately some questions about errors running Win ISI 4, when doing calculations or other issues, and all are related to configuration of Win ISI.
Click with the right bottom of the mouse in the Win ISI desktop icon:

And go to "Properties".Select "Compatibility", and mark the option: "Run this program as administrator".

Normally all the function of Win ISI will work fine after this step.
