To make screenshot in Windows 7, press the "Print Scr" button on your keyboard, open Paint (or any other image editing program), press Ctrl button and V together (or click on the "Paste" button in the menu above). Save the image, and the screenshots will be done.

As for the error message, I have no way of knowing what caused it. Did you unzip it with 7zip? Is your language for non-unicode programs still Japanese?
