Jade, what version of SAS/OR are you running and on what computing platform? SAS Simulation Studio has been included in SAS/OR on Windows since July 2009 (SAS/OR 9.22) and has recently (SAS/OR 14.3, Sept. 2017) added support on Linux. The catch is that the install for SAS Simulation Studio, a Java app, is a distinct step from the SAS/OR install. Often we've seen Windows SAS/OR sites not install SAS Simulation Studio simply due to oversight. During the install process, you need to be sure to check the box for SAS Simulation Studio. The good news is that if your site missed this step, it's fine to repeat the install process, checking only the SAS
Simulation Studio box. This will add SAS Simulation Studio without disturbing the rest of your installed SAS products.
