The license subsystem in Autodesk products reports possible errors in the form of [X.Y.Z], where "X" is the kind of a problem, "Y" is 1 (standalone license) or 5 (FlexLM license) and "Z" is the specific error (usually a negative number).
The "Z" error codes for FlexLM are as follows:
-1 Cannot find license file.
-2 Invalid license file syntax.
-3 No license server system for this feature.
-4 Licensed number of users already reached.
-5 No such feature exists.
-6 No TCP/IP port number in license file and FLEXnet Licensing service does not exist.
