find the “license.env” file in the bin directory of maya 2014. (C:\Program Files\Autodesk\Maya2014\Bin)

open that file with a text editor.

delete everything in the file (all the text) and replace with

MAYA_LICENSE=657F1
MAYA_LICENSE_METHOD=standalone

your license.env file should contain only these two lines of text, nothing else. Save and then launch the app.

Enjoy
