I downloaded the trial. Works fine. What is cost and how do I do about buying the full version?
The software is available from Mitsubishi Electric, but you will have to create an account and then get in touch with the developers because the application is not available for purchasing from the homepage.
You have the codes here in case you decide to buy: https://us.mitsubishielectric.com/fa/en/products/controllers/programmable-controllers-melsec/engineering-software/gx-works/gx-works2
There is no info on the price, though, but you can use the Contact button on the left side of the page.
