NX Starting the NX Launcher leads to a Java error
2021-10-06T23:27:35Z
NX System Administration
Summary
Details
Trying to run / start the NX Launcher:
Error message:
NX Launcher - system was unable to find the specified registry key for value.
Also, a Java error appeared.
To confirm, look under the Programs and Features list
IF 64-bit Java is installed, "(64-bit)" will explicitly be noted.
Example:
Java 8 Update X (64-bit)
2. Secondly, makes sure the NX environment sees that 64-bit Java via
the NX environment variable - UGII_JAVA_HOME
Define UGII_JAVA_HOME inside the ugii_env.dat file to make sure NX sees Java 64-bit.
a. Underneath C:\Program Files\Siemens\NX\UGII\
is a (text) file called ugii_env.dat
b. Open and edit the ugii_env.dat file, adding the UGII_JAVA_HOME value (example ONLY)
Notice the double quotes enclosing the path (especially for a path with a space like Program Files)
# Override any variables here.
UGII_JAVA_HOME="C:\apps\Java\jre8x64"
#
3. Next, test by launching an NX translator and make sure you successfully get to a translator start dialog.
Launching any of the NX translators in the Start -> Siemens NX menu is a very effective
way to confirm the NX environment sees the Java 64-bit configuration.
Start -> Siemens NX -> Translators IGES
If the NX translator presents the following start dialog, this confirms NX sees Java 64-bit.
Furthermore, the command prompt that appears when launching an NX translator will explicitly confirm:
"This meets or exceeds the minimum required version of 1.8.0_X"
4. Having confirmed the NX / Java 64-bit configuration is complete,
NOW try running / starting the NX Launcher again.
Summary:
In this particular case, a completed basic Java JRE 64-bit installation / configuration fixed the problem with the failed startup of the NX Launcher.
