Inventor renditions require the Inventor application to be installed on the server and currently consume an Inventor license.
Since 2019, Autodesk has release a read-only mode allowing user not to view and print 3D drawing without the purchase of a license.
Could the enterprise rendition module make use of the INVRO.exe instead of the Inventor.exe to render it's documents?

Need to investigate if read-only mode allows updating of properties for the title block sync.
