AutoCAD with updates (Update/SP, Bonus Pack).

To identify AutoCADu 2009 with installed updates (Update 1 or 2, Service Pack) and extension packs like the "Subscription Bonus Packs" you can use the dialog "About AutoCAD".

Run the command ABOUT (Help > About AutoCAD), click the "Product information" button and in the field "Product update" (SP) you can see e.g.:

• "AutoCAD 2009 - English" (the original version)
• "AutoCAD 2009 - English Version 2" (Update 1 - SP1 applied)
• "AutoCAD 2009 - English Version 2.1" (Update 1 applied, Bonus Pack 1 installed)
• "AutoCAD 2009 - English Version 3" (Update 2 - SP2 applied)
• "AutoCAD 2009 - English Version 3.1" (Update 2 applied, Bonus Pack 2 installed)
  

You can also use the _VERNUM system variable - the "Update 1" level will show "C.111.0", the "Update 1" plus Bonus Pack will return _VERNUM=C.112.0, the "Update 2" reports _VERNUM=C.608.0 and with the "Bonus Pack 2" then _VERNUM=C.662.0.
