Hi hes4l,
1. If you have not installed ie_spayed earlier, please double click on Install.bat file and proceed to the installation step directly by typing 2.
2. If you have run the MVPS.bat, the host file is installed automatically. You may not see any prompt telling you, but it is installed.
If you have any more doubts, please let me know, I'll try to help you out

.
