If attempting to run legacy SELECTseries 1 installations of Bentley Architecture, Structural Modeler, Bentley Building Mechanical Systems or Bentley Building Electrical Systems on Windows 8 or 8.1, you may encounter errors during startup since these applications were not designed nor tested on Windows 8. Since this is a software dependency, your options are to either downgrade your OS to Windows XP through Windows 7 or upgrade from your current legacy SELECTseries 1 building application to AECOsim Building Designer Ss5 that supports both Windows 8 and 8.1.
Two additional options are as follows:
1. The recommended solution, run a dual-boot on your computer. This allows you to install multiple operating systems to your machine. You choose which OS you would like to boot up with as the machine is loading.
2. The second solution is to run a Virtual Machine. This is an emulation of a computer system that mimics the functions of a real computer.
