compile errors for Due after updating to ver 1.68

Development Tools IDE 1.x
1

I updated from ver 1.67 to 1.68 and now can't compile any sketched for my Due.
The error message is below.
I have tried updating all the boards in board manager and all libraries with library manager.
I have completely uninstalled IDE and reinstalled. Still cannot compile.

Arduino: 1.6.8 (Windows 7), Board: "Arduino Due (Programming Port)"

exec: "C:\\Users\\Grizzly\\AppData\\Local\\Arduino15\\packages\\arduino\\tools\\arm-none-eabi-gcc\\4.8.3-2014q1/bin/arm-none-eabi-g++": file does not exist
Error compiling for board Arduino Due (Programming Port).

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

My Uno and trinket-pro sketches compile just fine.

Solved
completely uninstall version 1.68
delete director c:/users/../appdata/local/roaming/arduino15
reinstall ver 1.68

Did you try updating the core from board manager before you went that far? That might have been what it needed (and which was achieved inadvertantly after the clean installation).

Also, 1.6.8 is a step down from 1.6.7 on Windows - they botched serial handling, it resets most arduino boards repeatedly while the IDE is running. I'm still recommending 1.6.5r5.
