You should execute simseny.exe, next testsimseny.exe (see Figure 10, “Test program of the simulator.”). If everything goes, the simulator works properly.
Comment out code line where simseny_9112.h header file is included.
If program compiles, the problem could be that the header file is in a mistaken place. Verify the corresponding section.
If the program doesn't compile, the problem doesn't have relation with the simulator.
The installation has not been installed properly. Reinstall it.
