I'm trying to install Archicad 21 student version to my laptop*.
Near the end of the installation process, an error window pops up saying " ARCHICAD 21 installer detected that the operation system on this computer is out-of-date. Installation could not start. Please install the latest update and try again."
I reset the machine back to factory setting and install Archicad again but the same message pops up.
I've checked and the machine is running the latest updated version of windows10.

Most of the times this error message pops up because during the installation we run a small application that checks certain settings on the computer (to see if it is up-to-date) and this application is run from the 'C:\Windows\Temp' folder of the computer. The problem is that in some cases Virus-busters and Group-Policies prevent you from running executables from the temporary folder - thus the application will not run, and the installer will think your operating system is out-of-date.

If that's the case, either contact the administrator to lift this ban temporarily, or disable virus busters while installing (or any other application running in the background really, just to be sure).

I hope this solves your problem. If you have already solved this issue another way, it would be great if you could share with us, in case anyone else ran into the same.

You shouldn't be installing a cracked version - which is an illegal pirated copy.
Graphisoft may come knocking on your door now.

Why are you not installing a real version?
Don't you have a real license?
That will allow you to run old versions as well.

Cracked versions are not a good idea.
You never know what they may be doing to your machine in terms of security.

Also they are generally made from the very first build of a version and so will contain many unfixed bugs.

If you have a license, you can install any version you want (if the operating system allows it).
I have 18 running on Windows 10 with no problems.

If somebody else wants to run it and they don't have a license, then they can install the real version which will run in demo mode (no saving or printing) if they just want to look at files.
If they are wanting to do work, then they should be purchasing a license or using a spare one if you have it.
