Registration-Activation Error (204) - problem with Activation.

[Anonymous]

Hi Guys,

We have one license for Autocad LT 2006.

Unfortunately when I tried to get activation code (base on providing serial number) it giving me an error: "Autocad Registration-Activation Error (204)"

Last time when we've requested activation code was 08.02.2019 and was working fine.

But now is prompting again after almost a year to activate a product again. ( We didn't change/upgrade PC in that period of time). 

I've tried different way by AVA and I got this "The serial number you entered is for an older version that is no longer supported."

My question is why I can't get activation code this time where I was able a year ago? 

Also is there any other way to get the code?

I will appreciate for any help.

Cheers!

Autodesk no longer support registration of software older than three versions back. See the link below

There is a post on this board from earlier this week that might help.
