I'm trying to setup Archicad 12 on my lap top. Archicad program loads ok but when I try to update the software I get "Lib12-USA-2528 win.exe is not a valid win32 application". Same thing happens with the Hotfix updates. I'm running Windows7 Ultimate. Will be going out of town soon and I'll need to get some work down when I'm away. Any help will be greatly appreciated.
