Either use Twitch Launcher or vanilla.

Because they (you) have no permission to distribute Optifine.

The version of DynamicSurroundings you are using requires a newer version of Forge than you are using per the Changelog on Curseforge: https://www.curseforge.com/minecraft/mc-mods/dynamic-surroundings/files/2825354

Forge 1.13+ is currently not supported by the Launcher. No ETA for a fix.

The install file = the launch file. Save it to a location, because if you run it directly after downloading it gets deleted after you close the launcher.

Check your hosts file. It's on your C drive (C:\Windows\System32\drivers\etc). Use Windows Explorer to find it. Open with notepad, copypaste it to pastebin, put it here.

Remember that you needed to rename the forge.jar to modpack.jar? Rename it to just "modpack". Also, why is there a mods zip inside your mods folder?

What do you call "quite a long time"? It's quite normal for 1.12.2 modpacks to take well over 3 minutes to start.

So, it has been starting for about a minute in. Then it was killed. Did you close it, and why?

Their usual fix is either trying to update their intel drivers: https://www.intel.com/content/www/us/en/support/detect.html Or downgrading their java to 8u51/8u25: http://javadl.sun.com/webapps/download/AutoDL?BundleId=98428 Preferably in this order (if first works, don't do the second).

As soon as you would fix the zip, you would instantly get lots of errors due to all the version mismatches. You can't tell which versions you have, since 9mc is so lovely TO REMOVE THEM ALL. So yes, download everything from curseforge, if you expect any other help around here.

Hey, atleast we didn't put in crashing code for workarounds (we don't have any tho) like MultiMC did...

It would help if you stated what the modpack is.

Looks like you got ratelimitted. Try to search for modpacks on this site, instead of using the built in search.

Modpack no longer found at provided location.
