i have deleted any previos installer.
then, downloaded from this exact link:
http://files.minecraftforge.net/maven/net/minecraftforge/forge/1.7.10-10.13.2.1291/forge-1.7.10-10.13.2.1291-installer-win.exe
exact file name:
forge-1.7.10-10.13.2.1291-installer-win.exe
MD5 of the file:
0B8598A75955DEDF99A56E39C5C721CE
(again, i am not fully sure how to use this website. if i have done anything wrong, please explain how to do it.
