Delete  C:\Users\User\AppData\Roaming\.minecraft\libraries\org\scala-lang\scala-library\2.11.1\scala-library-2.11.1.jar and try again.

I have this problem as well, and i've tried this multiple times and it still gives me the same "Unable to save download. lzma-0.0.1.jar" error message when i hit "play"

Actually i fixed it, i went into "launch options" within the minecraft launcher, picked the forge profile, and set the version to 1.11.2. Wish I woulda tried that sooner...

That doesnt fix it, that just stops loading Forge.

And don't hijack other's threads.

I do Forge for free, however the servers to run it arn't free, so anything is appreciated.
