There seems to be an incompatibility with Microsoft EMET 4.0 when Alt.Binz is added to protected applications. When the user closes Alt.Binz program it will show "altbinz.exe Application Error; The exception Illegal Instruction. An attempt was made to execute an illegal instruction. (0xc000001d) occurred in the application at location 0x00000000. Click on OK to terminate the program" At the same time EMET gives a popup that SimExecFlow was detected for altbinz and the application will be closed.
