Installing a monthly update to an NX Continuous Release installation (NX 1847 and beyond) can result in the
SPLM_LICENSE_SERVER system environment variable being modified / reset to its original value. This can cause a licensing error when NX is started after an update is installed.
Solution
A workaround to this issue is to use the '
Licensing Tool - Environment Settings - Edit' option to specify the license server information. This information is stored in the Windows Registry entry '
Computer\HKEY_CURRENT_USER\Software\Siemens_PLM_Software\Common_Licensing\NX_SERVER', and as this value is used in preference to the
SPLM_LICENSE_SERVER variable, there is no adverse consequence if the license server variable is modified during the software update.
(Alternatively, the original license server information stored in the Windows Registry entry, '
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Siemens\NX xxxx\LICENSESERVER', can be modified to the required value.)
This issue is resolved in the NX 1899 Series - March 2020 Monthly Update (NX 1911).
The value of the
SPLM_LICENSE_SERVER variable will be retained.
