You can no longer activate 2014 and older versions of AutoCAD, especially in an unsupported OS like Win11. Sorry.

Mr. ZaCat,

I would contact Autodesk and see what they say. I know Mr. Pendean is right in they don't support it any more. But might be worth a try.

Note on contacting Autodesk. Ask the AI the question. They will fail and you will need to ask the same 2 or 3 times. Don't give up until AI does ask you the next sentence. It will then say do you need to speak to someone about your subject and you say yes. This will send you a contact email address and a request number. Email them and ask. I got my answer in 4 days. I like you I asked them on Thursday I believe so they have the weekend off. But they came back and gave me what I needed. 

Here is a link to previous request on the same subject:

Hope this helps.

Thanks, JRR!
