Currently, the latest version of MAX is 2.2
Typically, you want to find the latest version of NI-DAQ or NI-488.2 that supports your hardware. NI-DAQ and NI-488.2 will install MAX automatically. If you have an old version of the driver, it is recommended to uninstall the previous versions of the driver before installing the new one.
