One problem have been that there has been two license files used on the license server and when they have been correctly combined it has solved the issue.

Out-of-date version of the Autodesk Network License Manager (FlexLM)

Permissions to client side licensing components

PLIST information missing from the license file (AutoCAD 2007 and newer versions)

Missing/broken client side licensing components (AutoCAD 2007 and newer versions)

What's the solution to the error 1.5.-18, no valid license alert? There are countless reports of this error, & no fix forthcoming from AutoDesk.

Does this OPT variable appear in the license, some other file?

This is preventing our implementation of AutoCAD 2009. AutoDesk refers us back to our vendor...who knows less than nothing about FLEXnet licensing error debugging.
