System Requirements for the Autodesk Network License Manager

According to this KB article 64-bit Windows operating systems like Windows Vista 64-bit are not tested or supported for NLM based on FLEXlm/FLEXnet that Autodesk products uses. It doesn't mention Windows Vista 32-bit.

You probably can install and use it anyway if you read between the lines but according to a source at Autodesk "You cannot install it under 64-bit OSs.". If you have tried and it works add a comment. I know Windows Vista 32-bit works.

According to the Autodesk Network Licensing Guide for AutoCAD 2008 and other Autodesk 2008 products:

Make sure that your network license server meets the minimum recommended requirements. See the following table for hardware and software requirements.

Author notes: Update all tables with pertinent Windows Vista and 64-bit content.

Hardware and software requirements for the network license server
Hardware/software	Requirement	Notes
Operating system	Windows 2003 Server Edition Windows XP Professional, Service Pack 2 Windows 2000 Server Edition Windows 2000, Service Pack 4	The Network License Manager supports Ethernet network configurations only. The redundant license server model is supported only on Windows 2000 Server Edition and Windows 2003 Server.
Computer/processor	Pentium III or higher 450 Mhz (minimum)
Network interface card	Compatible with existing Ethernet network infrastructure	The Network License Manager supports multiple network interface cards.
Communication protocol	TCP/IP	The Network License Manager uses TCP packet types.

What is missing in the help file is that Windows Vista 32-bit is an allowed OS for NLM. It does not say anything officially about Windows 2003 Server Service Pack 2 (SP2).
