I agree with the above, any tech that is out there now ought to be more than enough to run R14, the downside, it may be too much. You may be into an uphill battle, Autodesk has stated that they will not be providing support to anything lower than 2013 on Windows 10, so if you have Windows 10 on this machine, R14 may not even function, and if it does, could be subject to errors and worse yet, Autodesk support wont be able to help you on it. You could try compatibility mode, but Windows 10 only has compatibility mode back to Vista.
