is missing from the .hdi file. The author himself has once appeared once, there is no specific solution, just give a direction, everyone can proceed Try it yourself.

3d cad software is a foreign software that requires quite high hardware and software platforms. The low version is such a requirement, let alone the 2014 cad drawing software. See the fault prompt, it should be software configuration. Higher, the driver can't keep up with it.

Personal suggestion If you want to use AutoCAD 2014, you can use WIN8 32-bit system, and then re-install cad 2010 or 2014 in win8 system should be able to solve. For reference, it may not be completely resolved.
