Hi @wcsaravanan.
Some additional information here......
Operator Advisor is now included with the installation of ThingWorx Manufacturing Apps 8.5. If you are installing a previous version of ThingWorx, Operator Advisor is installed as a separate extension.
The upgrade process from ThingWorx/Manufacturing Apps 8.4 to 8.5 can be complicated. Therefore, I recommend that due to changes that have occurred between Thingworx 8.4 and 8.5 affecting Manufacturing Apps/Operator Advisor, that you start with ThingWorx 8.5 and then install the Manufacturing Apps 8.5 extension which includes Operator Advisor.
Note that you must maintain consistency between versions. For example, if you are installing ThingWorx 8.5, you must install ThingWorx Manufacturing Apps 8.5. If installing ThingWorx 8.4, you must install ThingWorx Manufacturing Apps 8.4. While the installation may be successful if you mix versions, the functionality will be impacted. Here is a link to the installation instructions for Manufacturing Apps. Please start with these instructions which will call the ThingWorx installation instructions when you get to that point.
Lastly, please make sure you are conforming with the system requirements for the appropriate version.
Please let us know if you have further questions.
Regards.
