Keil PackUnzip.ece problem

Hi

I signed up for the stm32 course in which they use the Keil ARM environment. I downloaded the new version 5.38a and am trying to install it. In this course we are using STM32G0B uC but I am getting error from PackUnzip.exe during installation "this application will not run on your computer" as attached. My computer has Windows 10 32 bit. What could be the problem?
