4. 64 bit Operating System.
Minimum Certified Operating Systems

Windows XP and Vista

Windows XP support from Microsoft is ending and Vista was rarely deployed so these two versions of Windows are not supported by
NX 9. Siemens PLM Software has not performed testing on these versions and cannot resolve any issues related to NX 9 running on these operating systems. If NX 9 is deployed on these versions of Windows, any issues will have to be replicated on Windows 7 before filing an incident report.
Changes involving the client (where the NX product is installed) machine’s environment variables.

With the NX 9.0 version you are able to run all versions from NX 5.0 to NX 9.0. For clients with NX 8.5 down to NX 5.0 you will still use the old environment variable.

UGS_LICENSE_SERVER= 28000@<HostName>

Starting with NX 9, there is a new environment variable used on the client to point to the license server.

As stated earlier, older versions will run by using the old environment variable (UGS_LICENSE_SERVER) and NX 9 and versions moving
forward will use the new variable (SPLM_LICENSE_SERVER).  Both of these environment variables can exist on one client if you are running multiple versions.
