Using the latest installation file –

  • Uninstall Autodesk Desktop Connector

Did it launch?

Other things to try:

Logout from Autodesk services prior to starting Desktop Connector. You can do this easily with the sign out option at top-right of Autodesk Desktop App.

Through Task Manager – Details, attempt to “End Task” on these. Probably AdskLicensingService.exe won’t close.

Then try to start Autodesk Desktop Connector again from the Start Menu.

You can monitor starting of Desktop Connector in the tray.

 

Other errors that may pop up:
