NodeXL Pro requires:
OPERATING SYSTEM: Microsoft Windows ™(XP, Vista, 7, 8, 10)
SOFTWARE: Microsoft Office™ (2007, 2010, 2013, 2016)
64-bit versions of Windows and Office are recommended (32-bit systems cannot use large amounts of RAM).
RAM: More the better! 4GB is enough to handle very small networks, 8GB for medium networks, 16GB or 32GB is recommended for very large networks (100K edges and above).
CPU: Most computers are now fast enough to handle network calculations. That said, faster CPUs are good for improving NodeXL’s performance. However, currently NodeXL is a (mostly) single threaded application that does not make use of multiple cores.
