Did you download the Archicad 9 installation files?
If so maybe the download is bad or incomplete.
If it was a download then try downloading it again.
If it is on disk does the installation screen load when you insert it?
If not what happens if you try to run the 'setup.exe' file.
And why Archicad 9?
Is that all you have a license for?
I assume you are trying to install a proper copy and not a pirated one?
I would never trust those.
