Autodesk has released a new version of Infrastructure Modeler 2013. This version gives you the ability to put scenarios on AIM 360, which allows you to open in a web browser or a mobile device. This version is only available to Subscription customers.
You must uninstall the previous version of AIM in order to install the R2 version. Also, keep in mind that anything that was created prior to R2 will prompt you to update your database or make a copy. Once you update the database, you will not be able to open it in a previous version.
