 * Locate mugen.exe.
 * Right click on the program icon and go to Properties.
 * Go to the Compatibility tab.
 * Tick the checkbox by "Run this program in compatibility mode for:".
 * Click the box below and find any version before Win 8 (probably 7 will do you fine).

It should be noted that I know bugger all about Win 8, so said procedure may differ.
