Note

When using a command prompt to enter a command that includes the path C:\Program Files (or any directory name that has a space), enclose the path in quotation marks. For example: “C:\Program Files\rti_connext_dds-<version>\bin\rtilauncher.bat”. Or if you have defined the NDDSHOME environment variable: "%NDDSHOME%\bin\rtilauncher.bat".
<path to examples> By default, examples are copied into your home directory the first time you run RTI Launcher or any script in %NDDSHOME%/bin. This document refers to the location of the copied examples as <path to examples>.
