AutoCAD 2013 can easily be changed between Network, Standalone and Multiseat Standalone licensing with a small registry hack that has changed a little compared to earlier versions. (How to change AutoCAD 2012 from network license to standalone)
Start the Registry Editor and the registry location is HKEY_LOCAL_MACHINE\SOFTWARE\Autodesk\AutoCAD\R19.0 and then depending on AutoCAD vertical look in ACAD-B001 for AutoCAD 2013 or for example ACAD-B004 for AutoCAD Architecture 2013. Finally in AdLM there is Type that can be changed to any of the values 1, 2 or 3 as seen below.
1 – Network
2 – Standalone
3 – Multiseat Standalone
