How to fix MCreator Decompiling Test error (.exe) MC 1.7.9 ONLY

I DO NOT OWN THIS PROGRAM OR SUCH THINGS, I JUST SHOW YOU HOW TO FIX A COMMON PROBLEM!! ~FAQ Q: I dont have the fml folder! A: Check my steps correctly, make sure you are using .exe installation, make sure you have ran at least one time the installer with the error message Q:Cant find the Pylo folder inside OS (C:) A:You may be blind or you are just not using the "exe installation way". Q:The instalation is successful, but when i boot the program, the same problem appears again. A: Make sure you are opening the MCreator LAUNCHER and not the INSTALATION FILE. After you are sure you are not doing such mistake, reboot your computer/pc. Follow the steps AGAIN carefully. Reboot your computer again. If it does not still work, make sure that no files are missing, and that you have your "Pylo" folder inside your C: unit. It should now work, as well :) Q: I think there is a java problem, because when it stops, it says: "Searching for javac.exe in C:Program Files" 3 times and then there is an error. A:first of all install java SDK (Java Development Kit) , then add " C:Program Files (x86)Javajre7bin " on your computer&Environment Variables, section: Path . Well, if you could not understand what u need to do after reading this, refer to a tutorial video. *PS* : C:Program Files (x86)Javajre7bin is not sdk path, just install sdk and java runtime environment.
