Anyone every seen the Arduino IDE not kickoff avrdude but state that the upload

Anyone every seen the Arduino IDE not kickoff avrdude but state that the upload has finished? I’m running Arduino on a minimal windows 10 box. Is there some built in windows fu I might have accidentally removed? I assumed it would just be java making a syscall to kick off an external process but my knowledge of windows and the arduuno build chain isn’t as strong as I’d like.

OS: Windows 10 (minimized with NTLite so it will run on a netbook)
Arduino version: 1.6.11
Arduino type: Nano clone. CH340 chip for the usb-> serial (it does show up as a com port)

If you’re using 1.6.10, upgrade to 1.6.11 or downgrade to a prior version.
