Forge Installation Error

[BuddermanTheAmazing]

So, I've tried installing forge for 1.7.10, 1.8,1.8.9, 1.10.2, and 1.12 using both the recommended and latest versions in both the normal and windows installer, and I always get this error. This snip is specifically from the 1.7.10 installer. No one has tried to help me on the minecraft forum besides telling me to run the windows installer as administrator, but that didn't do anything. No one else has gotten a fix to this problem from what I've seen.

Logs or it didn't happen.

While you're trying to figure out how to avoid being ignored for not following the instructions, I suggest reading the only pinned thread in this section of the forum (hint: it has "READ FIRST OR YOU WILL GET BANNED!!!" in it's title for a reason...).
