I am having trouble installing archicad 18 for education. While it is unpacking the software it will just stop. I have uninstalled version 16 and can re-install 16 without any problem but cannot install version 18.
That sound like system problem. I downloaded mine online with no problem and it took more than one hr. check your RAM capacity and speed. A 2GB RAM will be sufficient. And use a( CA Cleaner ) to remove all the clog./trash.
