Unable to Install AutoCAD Architecture 2012 64-bit

When I attempt to download and run the program my system gives me an error message saying:


This program is not commonly downloaded and could harm your computer.


I select "Actions", "More options" and choose "Run anyway". The installiation begins but towards the end I get an error message saying:


Some installation files are corrupt.

Please download a fresh copy and retry the installation


When I close the window I see the following error in the installation window:


CRC failed in x64\ACA\Program Files\Root\acdb18.dll

Unexpected end of archive


If I close the window option, I get a popup saying:


This program might not have installed correctly


If I select "Reinstall using recommended settings", my system tells me:


The publisher could not be verified. Are you sure you want to run this software?


When I click "Run" the installation program starts over and at the end I get the same error as before.

Problems downloading the Autodesk software and/or CRC errors may be avoided by using another web browser, or using the alternate browser download method.

For more detailed information on this process, please see the following blog post tip here:
