This message means the ProductInformation.pit file cannot be found.

All Autodesk products must be registered in ProductInformation.pit
The ProductInformation.pit file should be here: 

  • /var/opt/Autodesk/Adlm/.config/ProductInformation.pit
  • C:\ProgramData\Autodesk\Adlm
  • /Library/Application Support/Autodesk/Adlm/.config

The product information file is created when you install an Autodesk product like Maya. 
And then when you install MtoA, the MtoA installer registers Arnold in the ProductInformation.pit file by running bin/pitreg



To use Autodesk licenses for Arnold when you batch render with Maya, Arnold must be registered in the Product Information file (aka the PIT file).

Normally the MtoA installer does this for you. But if you’re running Maya and MtoA from a network install, then Arnold won’t be registered in the PIT file.

To manually register Arnold in the PIT file:

  • MtoA includes pit/pitreg for registering Arnold in the PIT file, so you just need to run pitreg on the machine where Maya and MtoA are installed, like this:

    Succesfully added Arnold information to PIT file


If you're running everything off of a server (thin client), then AdlmThinClientCustomEnv.xml may set a custom location for the PIT file.
More information on thin Client for network licensing can be found here:


For other plugins, like C4DtoA, the plugin includes the PIT file that Arnold will use when it checks out an Autodesk license.
