Installing VirtualBox is very easy, but before you download the software, first check if your computer has enough resources to run the Test4Theory@home system. The computing requirements are modest for a modern desktop or laptop, but some of you may also have an old computer gathering dust that still could be re-used for the project.
Anyway, your computer will need at least 512 MB of RAM and more than 9 GB of free disk space for hosting the experiments. If your computer does not meet these requirements, the project will not send you any jobs, sorry! But if you do have those free resources, you are ready to start.
First step: download VirtualBox from the official web site for your operating system (and please make sure you choose a recent 4.1.x version):
Once you have downloaded it, you will have to install it by double-clicking in the installer and following all the steps of the installation process.
After installing Virtual Box you do not need to launch or run the VirtualBox application or create a virtual machine yourself. T4T will manage that on its own.
Next step: You must now set up BOINC - go to: the installation of the BOINC client.
