In the 10.3.1.1026 version of Operations Dashboard (July 2015 release), we only supported 64 bit systems. In the past several weeks, we have had a lot of customers indicate they would like support for the 32 bit systems as well. We are currently testing an updated release that will support both systems.
This new version will be out this week sometime. When it comes out, I will update this thread, but you can also check the home page or the Apps Blog site for additional information.
Thanks!
Chris
