Hi Steven,
The DemoSimulatorPackage.zip is the one officially released. I am not sure how they got the other packages/files. This package has everything it needs as follows. (Learning Workshop 1)
1. DemoFactorySimulator.opf is the Kepware Project file which contains lines/assets and tags for those assets are simulated.
2. DemoFactoryDataSet.zip. This contains all the assets / lines which are bound to the Kepware project. Users need not create them.
3. data-0.twx is the Thingworx data file which creates the Streams
4. KepwareSimulatorControl.zip is an sample app which allows to control the Kepware tag values from the app.
5. There is powerpoint and pdf which provides instructions to install and usage.
Thanks,
Varathan
NOTE: Steven, I added this information from our conversation to make sure it is out there for others as well.
