Launcher not launching?

[LexiiSparklez]

I've updated the launcher, closed it and reopened it, made sure I had ran 1.11.2, everything I could think of. It gives me the error in the log:

Spoiler: error message

And then it terminates the process :/

Try installing the most recent version of Java here; make sure to get the x64 version. Then try doing a "soft reset", i.e. go to %appdata% and delete the WesterosCraft folder, and then try Updating the launcher again.

See here for more troubleshooting info.
