I had the same issue due to sass setup in the project, In my case I had to change below line

"gulpStartupTasks": [
  "sass",
  "watch"
]

to 

"gulpStartupTasks": []

in ionic.project file

I had the exactly same problem with you.(HATE WINDOWS!)

And happily I found the solution about this, please follow the steps below:

  1. Open C:\Users\*YOUR USERNAME*\AppData\Roaming\npm\node_modules\ionic\lib\ionic\cordova.js

  2. Goto line 40, and
    replace
    var cordovaCmd = spawn('cordovaz', cmdArgs);
    to
    var cordovaCmd = spawn(process.platform === "win32" ? "cordova.cmd" : "cordova", cmdArgs);

  3. try ionic run android again!
