By default WhereScape 3D installs it's own 32-bit Java runtime and
starts as a 32-bit application - this is for compatibility with
WhereScape RED.
However, you can run 3D as a 64-bit application if you wish. To do this
you will need to first have a 64-bit version of the Java runtime
installed and then follow these steps:
- In the WhereScape 3D installation folder (e.g. C:\Program Files (x86)\WhereScape 3D\), copy the files "JdbcOdbc.dll" and "ntlmauth.dll" from the "x64" subfolder into the root installation folder, overwriting the existing files.
- Start 3D using a command line that invokes the 64-bit Java runtime and the 3D jar file, e.g.
C:>"C:\Program Files\Java\jre1.8.0_51\bin\java.exe" –Xmx1024m -XX:MaxMetaspaceSize=512m -jar "C:\Program Files (x86)\WhereScape 3D\WhereScape-3D-HEAD-bundle.jar”
To revert to 32-bit operation, repeat step 1, but copy the files from
the "x86" subfolder instead.
Note that if you start 3D in 64-bit mode you will not be able to access any 32-bit ODBC DSN you may have previously created with WhereScape RED.
