installer.jar.log: https://paste.gg/p/anonymous/a0fef6c8ec6c46d999ebe4a93b78bce0
I tried using the installer from both the latest and stable builds (did two separate downloads of each) and kept getting the same error each time. I have checked and my java is the latest version of java 8, and my install of the game is completely vanilla and up to date. If it matters at all, after the installer crashes it doesn't exit and a window briefly flashes containing text that look like the beginning of the log file maybe, except it only flashes for a split second making it hard to tell, then it just keeps running unresponsively.
