PRISM will not run on any 64 bit operating system. The simplest path for Windows 8 64 bit users is to make use of the virtual machine (VM) software built into the operating system.
In order to set up a VM, sufficient space is necessary on the host PC hard drive - at least 25 GB and ideally 50 GB is necessary. In addition, the user needs a valid copy of any WIndows 32 bit operating system: XP; Vista or Windows 7.
First, the PC needs to have virtualization enabled in BIOS. Go to BIOS setup according to your PC's method. In BIOS setup, go to "Security" and enable "Virtualization Technology."
Accept, and save settings and allow the PC to start.
Once started, in Control Panel, open "Programs and Features." On the left side click on the option "Turn Windows Features on or off."
When you get to the next screen, check the box under "Hyper-V" and click OK.
You will be asked to restart. Restart the PC- it will behave as if it has received a large update. Once it is complete Hyper-V Manager will be in your list of programs.
Start Hyper-V Manager and follow the "New Virtual Machine" installation instructions.
This will include installing the operating system, either through a DVD drive or an ISO file. When complete, the VM will appear in a new window and look exactly like the start screen for whatever operating system was installed. At this point, the VM will have no connectivity to the internet and will only show the DVD drive as an accessible drive.
It is possible to link your host machine drives and the internet to the VM, however the specifics of how to do this varies depending on the host PC. In general, a "Virtual Switch" needs to be installed to access the internet. After clicking on “Virtual Switch Manager” in the Actions pane ensure that “External” is highlighted, and then click on the “Create Virtual Switch” button.
It will ask you to select the hardware device that connects your host PC to the internet. Select the NIC applicable to your machine. Here is an example:
A similar procedure is necessary to link hard drives.
