I've recently change my computer to MacBook (2018 MacBook Pro with Mojave update) and I wanted to install Archicad on it. I am studying so I applied for student version, I got the licence, downloaded matching software ( INT 22 version for Mac). And here starts the problem. As I am typing the serial number the 'OK' sign shows, but right after I click "Restart ArchiCAD" there is error with information "Serial number validation failed". I tried several times, restarting computer, checking if the serial number fits, but everything is ok.
I also tried:
installing PL Archicad 22 for Mac - same error
Installing 21 Archicad - it is also showing same error
I really don't know what is the problem, I'm thinking maybe there is some issue with archicad connecting to server and Mac is blocking it... But I couldn't find any proof for that on the internet so please help
Hi! Did you solve the problem? Can you tell how you did it ? Because I got the exact same problem. I can’t open Archicad on my laptop. The serial number is working on my pc but not on my laptop
Would be great if you can tell me how you solved it!
I know it seems very trivial, but it is worth checking, because most of the times this is the solution:
Please make sure when you choose to enter a license number that you choose "Educational License", and not "Trial License". It is easy to make this mistake, and if you enter an EDU code for the Trial dialog, it will not work.
When you copy-paste the license number, it can easily copy unnecessary spaces and dashes with it, so please make sure to double-check, that everything is entered correctly.
If there has been a delay between entering the license number for your first and second computer, it is possible that the license is already expired.
It is possible that you accidentally installed a different version on your computer (e.g. the International, the New Zealand, the USA, and the UK version are all english, but they require different licenses. make sure you have the right version installed and you have a license for the same version.
If none of the above work, please send me your e-mail address in a private message (the one you used to register on myarchciad.com), so that we can check your license availability in the system.

Hi! I'm currently having the same problem but with Archicad 24 on Mac. I already confirmed that the version of the program matched my educational license and that the code was well written...but then, when the program asked me to restart it to activate the license, it said that the serial number validation failed.
Any suggestion on how to solve this problem?
