Why am I getting an error about Non-commercial (Apprentice) assets not allowed with commercial licenses?

It's possible that you have the non-commercial version of those dependency assets in the HOUDINI_OTLSCAN_PATH which could be why the dependency assets are not loading. Depending on your operating system, they could be in the following paths: Windows: C:\Documents and Settings\\My Documents\houdini15.5\otls C:\Users\\Documents\houdini15.5\otls Mac: /Users/username/Library/Preferences/houdini/15.5/asset_store/user/otls Linux: /home/user/houdini15.5/asset_store/user/otls You might have to copy the commercial version of those dependencies into the OTL directory manually.
