1.6.4 is no longer supported on this forum due to its age. Please update to a modern version of Minecraft to receive support.

I'm going out on a limb. This looks like a certificate error and I've had certificate issues before because of a "Security Feature" from Comcast (my ISP) that was done poorly and was replacing a valid cert from the website with an invalid one from Comcast.

Far as I know NetGear isn't an ISP, though they probably are the company that made your router

Did you do anything to JourneyMap recently?

What internet provider do you have?

You're trying to run Thaumcraft for 1.8.9 in 1.12.2, this is not going to work

ModLauncher is not something you install manually, it's essentially the middleman between the Minecraft Launcher and Modded Minecraft, Forge installs it automatically.

I don't think Optifine loads as a Forge mod anymore, I think it loads as a ModLauncher plugin.

Follow the video above and tell me what it says

The filenames of one or more of your mods suggests you got them from a repost site. Please read up on the StopModReposts project (link in my signature) for info on why this is a bad thing.

Please provide a fresh launcher_log.txt

I would assume you're looking at the instanceof check, and as ItemTippedArrow extends ItemArrow that will pass, what stops it is ItemArrow's implementation of the isInfinite method which does directly check for ItemArrow, so if you make a custom ItemTippedArrow that overrides isInfinite it will work.

Try running the launcher again

Ok, File Explorer is hiding file extensions from you, to show them go to View and Check the box that says File Name Extensions. After that just make a text file but change .txt to .json and write null in it

This can be done through registry replacement (i.e. creating custom Tipped Arrows and replacing the vanilla ones)

I would guess you downloaded a file from some sketchy site that asked you to install a bunch of adware. Run a virus scan then install Forge from the proper place.

Why do you have a 1.7.10 server jar in there? create a file called launcher_skins.json in there and in it write "null"

Please provide a screenshot of your .minecraft folder

Have you tried removing Optifine?

Try the latest version of Forge instead of the Recommended

Do you have McJtyLib installed?
