Cannot start start AutoCAD 2023 after installation, dialog box says License Manager is not functioning or is improperly installed. AutoCAD will shut down now.

I’m hoping someone at Autodesk/AutoCAD can resolve an issue with my installation of AutoCAD 2023.

I enrolled in an AutoCAD course with the University of Guelph in the spring of 2022. The course 310-1035 Computer Assisted Design I started on May 6, 2022.

Unfortunately, due to family matters I withdrew from the course on July 30, 2022. Subsequently the program was disabled, and I deleted the program from my computer.

Later, I enrolled with Ryerson University (now Toronto Metropolitan University) for the course CKAR 215 Computer-Aided Architectural Drawing using AutoCAD.

The course started Sept. 15th and provided a link to download AutoCAD. I downloaded the program but have not been able to start the program. A dialog box appears stating License Error.

The License Manager is not functioning or is improperly installed. AutoCAD will shut down now.

Also, I received a letter from Autodesk stating that my educational expires on May 6, 2023 which makes me think they assume I am still using the program I downloaded for the UofG course.

I would think with the new course from TMU the expiry date should be around Sept. 15, 2023 or thereabouts.

Note: I used a different email address for the TMU course don't know if that affects the process.

To quote the Beatles: HELP!

P.S> I copied copied a couple of screen shots but i got a message saying invalid HTML in message so I deleted them.

I had to uninstall the license and re-install the license app THEN update it.
