Why do I get the error "Cannot open source file: 'windows.h'" when trying to compile a model Simulink (R2013a)?

Hello Users,

I am facing an issue while Compiling my Simulink Model containing ASCII Encode block.

(F) C0005; "C:\PROGRA~1\MATLAB~1\toolbox\rtw\targets\xpc\target\build\xpcblocks\asciiencode.c", line 20 pos 21; could not open source file "windows.h" #include windows.h ^

I am not familiar with this situation. Can anyone please help me with this?

Best Regards
