The last time I went to the hardware store I saw two different sets of twins, and the night before twins at our basketball camp.
AutoCAD historically makes major changes to AutoCAD every three years. You will notice that applications like ArcGIS for AutoCAD list support for AutoCAD in spans of three years also. The latest version of ArcGIS for AutoCAD 300 Sp1 includes two of those three year spans namely 2010-2012 and 2013-?. Since 2014 wasn't released when this newest version was built it is not listed explicitly as supported. I use ArcGIS for AutoCAD on 64bit AutoCAD 2014.
