+Examples of currently not supported elements:
++ exceptions (if the executable you converted will be run as a shellcode, and throw the exception, the appropriate exception handler will not be found, and the application will crash)
++ Delay Load Imports (only the basic Import Table support is implemented)
++ MUI files (if the executable you converted expects some elements of the GUI have to be loaded from a MUI file, it won't work)
