Is it possible if I want to run WPI application without Windows installer from USB? It means that, I don't want to use or don't have any $OEM$ folder root in my USB. When I directly paste WPI folder into USB and I tried to run the application, the GUI gone blank. It hasn't happened when I accessed it on my HDD. I really want to use it in the USB without Windows installer in it. Is the solution that I have to make my USB bootable first? Or there's another way to solve it? Any suggestion? Thank you in advance.
