The Adams/Controls installation on Windows 64-bit machines will not function as expected in co-simulation mode because a file is missing from the installation.

Preferred Solution:

This issue has been fixed in Adams 2012.1.2 and later. It is suggested to install one of these later versions of Adams if possible. If this is not possible, see the workaround below:

Workaround:

To fix this problem please download the attached library file named adams_plant.mexw64 (from Adams 2011, but works with Adams 2012) and install it in the directory: 

C:\MSC.Software\Adams\2012\controls\win64

This assumes that your Adams installation resides in the directory above. If not, find the equivalent location on your own machine and place the attached adams_plant.mexw64 file in there.

Notes: 

 - Adams 2012 on Windows 32-bit machines is working as expected; this article applies only to 64-bit installations of Adams.
