Our entire catalog for both ConfigMgr and Intune is currently imported as a CAB file, which imposes a 2GB maximum size limit per application. The latest Inventor Professional 2027 update is over the 2GB limit. We are in the process of rebuilding the backend to eliminate this restriction. However, due to the complexity and number of moving parts involved, we do not yet have an ETA for completion.
As a workaround, the update can be distributed through Custom Apps, which does not have the 2GB file size restriction.
