For those that read the README (that should be everyone!), you may have noticed that Infrastructure Modeler is not supported on XP, and won't install if you try.
For those of you installing AIM from the Building Design Suite (but not Infrastructure) you may find that deploying the entire suite to XP fails. This is due to having AIM in the list of products selected for install. For a solution, please go to usa.autodesk.com/getdoc/id=TS19352282.
