Indusoft Web Studio is now AVEVA Edge. Same product, just a different name.
You now have to buy it through an AVEVA distributer and use AVEVA customer support. AVEVA Edge fits in with their larger suite of software offerings.
The price is also a little higher, but still way below all of their main competitors.
We'll see how this goes.
