Unity 5. Command Invocation Faliure

This question seems to get asked a lot because this error seems to cover a multitude of problems. None of the answers I can find on here or else where apply to my problem.

Here's the full error:

CommandInvokationFailure: Failed to re-package resources. See the Console for details. C:\Users\id\AppData\Local\Android\sdk\build-tools\24.0.0\aapt.exe package --auto-add-overlay -v -f -m -J gen -M AndroidManifest.xml -S "res" -I "C:/Users/id/AppData/Local/Android/sdk\platforms\android-23\android.jar" -F bin/resources.ap_

This is a new install for Windows 10 and the error happens on an empty project as well as the one I had working before. I'm reasonably sure I've got the JDK and Android SDK set up right but I could be wrong.

I've tried reinstalling Unity. The android SDK is up to date and I have JDK_HOME set for the root of my JDK.

Any pointers or hints appreciated.
