Working with ESP8266, had issue with Proxy here at work, once I fixed proxy, JSON link added in pref started working, I shut down and restarted IDE, shows splashscreen but will not launch.
I have uninstalled, reinstalled dozen times, deleted all directories associated with Arduino. NO change. IDE will not work (HOWEVER, version 10.0.5R2 still works).
I am a rookie Arduino user, below is output from Arduino_debug; Any help is appreciated.

I have tried several other things I have seen posted. Appears I am not the only person this happens to. This is crazy! I have never seen a piece of software that cannot recover from crash with a uninstall, delete all trace and reinstall.
I have no idea what to try at this point other than wipe my OS and reload, which I find ridiculous.
Best bet for using ESP boards is 1.6.5 r5 zipped version.
Some ESP boards work for me under 1.6.9 but anything above that has issues and not just with ESP's if you took the time to read the amount of negative (but true) posts about 1.6.10.
Get a copy of 1.6.5 and unzip it and set up a shortcut to it.
Works every time here on a variety of ESP's
Set up 1.6.9 for Arduinos only.
Well, good news and bad news;
went to 1.6.4 since 1.6.5 does not support proxy internally; I go this error;
Illegal character ((CTRL-CHAR, code 0)) : only regular white space allowed between tokens at Blah blah blah... I can add detail on request.
After, 1.6.4 will also no longer start up. So this is kill each in succession.
I double checked that I did not put any white space in entery.

Had not noticed you were using a proxy.
Use VPN's myself with no issues.
Yes please include some verbose output.
Did you run 1.6.4 from an UNZIP location (not installed) ?
Also what sort of clean up have you been doing after an un-install of an IDE ?
Just using the regular uninstaller leaves a folder behind in one of two locations depending on the IDE installed.
Look up some of "pert" posts he often mentions them and they often fix issues.
EDIT here are the locations I got from Pert.
On Windows:
Arduino IDE 1.6.5r5 and previous:
C:\Users(username)\AppData\Roaming\Arduino15
Arduino IDE 1.6.6 and later:
C:\Users(username)\AppData\Local\Arduino15
I also move my sketches location away from my documents folder as I hav had a couple of issues in the past.
I also use CCLEANER after an uninstall then WISE registry cleaner as well to dig out any remnants of a past IDE
Great news, hidden locations did in fact harbor hidden files. Once folders were deleted, version boots.
Proxy is working but took about 5 tries to get it to sync up. Not sure what this is about.
Anyway, thanks for help.
