Download the Windows or Linux OAS installation here.
On Windows run the downloaded Setup.exe file to install one or more of the Open Automation Software features. Select the default Typical installation if you are not sure what features to use or the Custom installation if you want to save disk space on the target system.
When prompted agree to the End User License Agreement to continue the installation.
When the installation is finished the OAS Service Control application will appear if the OAS Service was installed. Use this application to start the 4 Services. If this is the first time installing the software it will automatically enter Runtime with an example Tag Configuration.
If you restart the computer the OAS Service will automatically start. You can change the start mode of the OAS Service using the Service Control Manger built into the operating system.
To install on Linux view how to Setup OAS Engine as a Linux Service or Daemon to extract the OAS Engine files to any directory of choice and run the OASEngine.
