Is there any way to bump this? just ran into the same issue after updating. can we at least get the file to roll back our launcher? or would that not work for minecraft?

I can only launch forge profiles through MultiMC. Using the native launcher and the jar version do not launch forge profiles

Dominator465 2017-10-25T15:38:58Z

There is a new version! It's fixed! Horray!

thanks for the quick fix mojang. up and running on windows 10 for me!

migrated 2017-10-25T17:39:11Z

Still not working on linux!

I'm on windows 7 and it's still not working

This bug report is incomplete. It is also currently affecting linux launcher version 1.6.82-j with the same error set.

This is affecting all modded and vanilla profiles, with the sole exception of being able to launch the 1.13 snapshot 17W43.
This is now two hours after forums have reported the windows version as 'fixed', and it seems both linux and mac users are still pending an update.

Can still confirm it doesn't work on linux, only works on the newest snapshot!

migrated 2017-10-25T19:10:26Z

Just wanted to say for all linux users! You can download then newest version of the launcher here:
https://www.reddit.com/r/Minecraft/comments/5opl31/help_us_test_the_new_minecraft_launcher_now_with/
It works for linux too, so it may probably be a work-around before the bug gets fixed!

@ Domenico Rotolo : Saying something will magically work, and it actually working are two different things. The 'new launcher' installs, but will not open for me. That is also a 9 month old reddit post, so it has nothing to do with the currently broken launcher version provided directly from Minecraft.net.

The newest launcher java-free works fine for me on Fedora and it is not affected by this bug

migrated 2017-10-27T11:49:21Z

This is still an issue for me with the Launcher 1.6.84 and 1.6.84-j on Vista 64bit, latest Java.
I can't run 1.7.10 forge, still getting this Error: Could not find or load main class net.minecraft.launchwrapper.Launch

migrated 2017-10-29T12:43:42Z

Isn't it possible to distribute the 'old' version again that was still working on Tuesday before the snapshot came out? It's pretty annoying that people can't play in their modpacks since five days now!

migrated 2017-11-04T16:36:32Z

I can't believe this still isn't fixed. What have you been doing the last 10 days?

One could get the idea that it is intentional that modded games can't be run anymore...

galaxy_2alex 2018-04-26T00:34:13Z

Does this issue still occur with the latest version of the launcher?

migrated 2018-04-26T20:38:04Z

I'm not getting any later versions of the launcher than 1.6.84-j. "No update found."

migrated 2018-07-20T23:53:35Z

I'm having the EXACT same issue with the latest version 2.1.2118!!

I've updated yesterday to get the new 1.13 content, but now I can't open ANY profiles with custom mods in it. (for example, FORGE 1.12)

no crash log was generated (it seems the new launcher won't even launch the game!), just the attached launcher log:

migrated 2018-07-21T10:24:20Z

Also still not working for me, despite the fact that I now have launcher version 1.6.89-j as the latest available.

The launcher doesn't even try to start a modded version, it's downloading some stuff and then acts as if I haven't even pressed Play.

I'm just happy that I have a friend who programmed his own launcher, meaning I can continue playing this great game.

Please find my launcher log attached as well.

It's a year now that the official Minecraft launcher stopped launching the game... Latest installable version is 1.6.91 - any chance this'll be fixed SOON?!
