Why convert MUI to EXE?
Windows MUI resource files introduced in Vista are resource-only DLLs holding translated strings, menus, and dialogs for one locale but containing no runnable code. A .exe is a Windows PE binary with an entry point and executable code sections. Because a .mui has none of that content, no conversion is possible - the raw material simply does not exist in the source file.
