I've been getting an error message every time I try to start minecraft, no matter what version or file, it crashes after I click "play" on the launching screen
Computer Specs
Processor -> Intel® Core™ i3 CPU M 370 @ 2.40GHz × 4
Graphics -> Intel® Ironlake Mobile
OS type = 64-bit
Error Message
Error: Could not find or load main class net.minecraft.launchwrapper.Launch
please dont say reinstall minecraft or turn off and on your pc ive tried that over 5 times :I
Same problem here, just started today. Running Fedora 25. I've completely deleted my entire .minecraft folder and downloaded a fresh installer from minecraft.net, but I still get the same error. I did it again, and this time if I try to run beta 1.6.6 it gives the launcher wrapper error, but if I try to run a modern release (1.12.2) it says:
Error: Could not find or load main class net.minecraft.client.main.Main
Another note: I ran Minecraft in debug mode using my modding environment (Forge 1.11.2) and it ran just fine, so it's obviously a problem with the vanilla launcher.

I'm having the exact same problem, Did you use the new launcher or the old one?
Launcher Info
1.6.82j
Old launcher
woops meant to say new launcher
[deleted]
Same problem here, just started today. Running Fedora 25. I've completely deleted my entire .minecraft folder and downloaded a fresh installer from minecraft.net, but I still get the same error. I did it again, and this time if I try to run beta 1.6.6 it gives the launcher wrapper error, but if I try to run a modern release (1.12.2) it says:
Error: Could not find or load main class net.minecraft.client.main.Main
Another note: I ran Minecraft in debug mode using my modding environment (Forge 1.11.2) and it ran just fine, so it's obviously a problem with the vanilla launcher.
Thank you, this helped and fixed the problem
