Which version of NVivo 9 should I install: the 32-bit version or the 64-bit version?

A 64-bit version of NVivo 9 was made available in January 2011, and it can only be installed on computers that are running the 64-bit version of Windows 7.

The 64-bit version of NVivo 9 handles your computer’s resources more effectively, so you may see improved performance when working with a large amount of materials (sources) and themes (nodes).

Both the 32-bit version and the 64-bit version of NVivo 9 contain a small number of known issues which are listed in the FAQ: Are there any known issues with NVivo 9?

However, there are some additional known limitations with the 64-bit version of NVivo 9:

  • Some video files with .mov or .qt extensions may not play
  • You will not be able to change the automatic layout of models

If you're currently using a 32-bit version of NVivo 9, and you choose to install the 64-bit version, you must deactivate and uninstall NVivo 9 prior to installing the new version.
