Label error when running AX 2012 for 1st time after installation

Sometimes I am getting an Label error just after a fresh installation of AX 2012 when it should show screen for prerequisites i.e,compilation etc. Its a complete installation including AOS. I got a temporary solution for that as… if we open a New workspace from the same screen then everything goes fine… But my question is why that error is appearing at all. Here is a ScreenShot… enter image description here


Have you done the full compilation and full CIL.

If not please do it first.
