Install VirtualBox After you install the program, you may have to restart.

Another quick note: the iso file is large, and the virtual machine software can be somewhat taxing on your computer, so if your “host” computer is old and without space, this might not work for you. Take note of where you store the file, you’ll need it later. So download the Windows 7 32-bit image: it will be a *.iso file. Anyway, if you are trying to work with the EPA Water Treatment Model as I mentioned above, you will want a 32-bit Windows operating system, and I found Windows 7 to work just fine. If you are a student, visit this link, log in with your CU Identikey and Password, click the gear in the top right, “Office 365 Settings”, select “Software”, and you should then have the download page for Office 365 available to you. If either of the links are outdated, or you are at another institution, do an internet search for the office of information technology and see if your institution has a site license. The current link to download Microsoft Software is here for faculty and staff. For University of Colorado Boulder students and faculty, you have access to various versions of Windows software for free online.

Obtain a copy of the operating system you want to install.

For example, if you are sitting at a Windows machine, make sure to download VirtualBox for Windows. Be careful when you are downloading VirtualBox: select the proper “host” computer. The computer that you are actually sitting and working on is the “host” computer, whereas the computer you will set up later will be called the “virtual” computer. Essentially, this program sets up an entire new “virtual” computer within your computer, so you can install different operating systems, etc. VirtualBox is free, and seems to work well with what we’re doing, but note that there are also other virtual machines as well. Download VirtualBox which is the virtual machine software.

For example, a collaborator of mine uses the EPA Water Treatment Plant model which only seems to work under 32-bit versions of the operating system.

In this post, I’ll talk about how to set up a virtual machine on a PC, in order to run outdated software that may have been optimized for a different version of Windows.
