Cascade Licensing allows a product to obtain a license from a network license manager pool when that license manager is servicing more than one product. Cascading was implemented primarily to address mixed-product environments where both suite and base products co-exist. For Autodesk products that are included in a product suite and are also sold as an individual product, licenses are allocated based on a sequence of priorities defined in a PLIST (priority list). This PLIST increment was included and readable (sort of) in the license file.
For the 2010 products, the PLIST increment is no longer include in the license file but is now stored in a new external file named ProductInformation.pit. License files will still include PLIST increments for legacy products, however 2010 products will reference the ProductInformation.pit file for the required PLIST information.
The ProductInformation.pit file is automatically created on the local machine when a product gets installed and there will only be one ProductInformation.pit file, shared by all installed products. The file is created when the first 2010 product is installed and is appended to with each subsequent product installation. Likewise, when a product is uninstalled it unregisters itself from the ProductInformation.pit file. When the last product has been unregistered from the file, ProductInformation.pit is automatically removed from the machine.
The ProductInformation.pit file is created on the workstation in the following locations:
XP: C:\Documents and settings\All Users\Application Data\Autodesk\ADLM\ProductInformation.PIT
Just as with other licensing components, the ProductInformation.pit file should not be moved from its default location. In addition to the PLIST increment, the ProductInformation.pit file contains other licensing information for the installed products and a 2010 product will not run correctly without this file. We continue to deliver license files as these are still required for network licensing. With the exception of the PLIST, the ProductInformation.pit file does not contain PACKAGE information or any other information that is normally included in the license file.
Since the ProductInformation.pit file is encrypted and unreadable, you can no longer inspect the PLIST to determine the cascade order for 2010 products. You can obtain that information from the following technical solution:
