Serial number not working when typed in.

[Anonymous]

I type the correct and corresponding serial number into the boxes to launch AutoCAD LT I have reinstalled, it even gives me a green check mark, and I click activate and it loads a couple seconds but returns to the same page to retype the serail number and loops through this. Never gets to the window to type the activation code. What could be the problem?

Hi @Anonymous Welcome to Autodesk Community!

Could you attach a screenshot of the page where you entered serial number and product key?

For licensing assistance, it's best to contact the Activation and Registration team through our Contact Us page. Please be sure to select a sub-topic at the bottom of the page so that the contact options become visible.

This is where I type it in and click activate.

Hi @Anonymous

What I would suggest is a clean re-install (here's how). It looks like some files may have been left over from your previous installation.

Please, try the steps on the link above, re-install with admin rights and let me know if it works.

Thank you,
