My office is using network versions of Revit 2010 & AutoCAD 2010 from the Revit 2010 Architectural Suite package. Recently out of the blue, AutoCAD 2010 stopped working on my laptop. Whenever I tried to run the program I would get FlexLM error code -5.412.0. I looked this code up, and the -5 indicated that no such feature exists in the license file. But for some reason Revit 2010 can get a license. I un-installed both applications and re-installed them from the deployments on the network. Same thing, Acad cannot get a license but Revit works just fine.

Any thoughts
