Resolving Network License Issues in Revit 2012 with RPC Content

The Problem
Unable to connect to your ACM on your Network when using Revit 2012. While Autodesk is reviewing this issue, a customer presented a workaround solution to access your ACM. Mike Hart of Centerbrook Architects and Planners, LLP found a fix that will have you successfully accessing your license from across the network with just a few clicks.

Applications like Revit have a configuration dialog where the location of the ACM is specified. When this information is provided a file called rpcapi.ini is written. This is normally written into the local user profile in the Autodesk Revit Architecture 2012 folder. While troubleshooting and testing with Mike, he discovered that by copying the ini file into C:\Program Files\Autodesk\Revit Architecture 2012\Program the issue was resolved.

The Cause
After a little further research I determined the cause of this behavior. When changes are made to RPC configuration in Revit, an rpcapi.ini file is written to %appdata%\Autodesk\REVIT\AUtodesk Revit Architecture 2012. The issue lies in the fact that at render time, Revit is looking for a license and not checking here.

The Solution
Configure the ACM connection in Revit (under the Render Settings found in Options) and then copy the rpcapi.ini file created from %appdata%\Autodesk\REVIT\AUtodesk Revit Architecture 2012 to C:\Program Files\Autodesk\Revit Architecture 2012\Program. Once the rpcapi.ini with correct configuration information is located in this directory Revit will be able to access the license the next time that it is initialized.
