Alright, so I have downloaded forge thousands of times before the installer. But whenever I tried using the installer it just gives me an error saying "Corrupt download detected cannot install."
How do I fix it?
And if there is no fix, how do I manually install it?
I've looked around, not only on this site.
EDIT: No matter which build I select it just says the same thing. I also re-installed MC but of no avail.
Thanks,
