PhotoKey is a legacy product that is no longer in active development. We provide support for 12 months after purchase but are not able to continue supporting products that have been discontinued for over a year.
As long as the computer you are using it on is not updated to an operating system that PhotoKey needs to run, your software will continue to operate as expected.
I would also take a look at the Imerge Pro software that has the green screen feature as part of that, you can demonstrate that FOC by downloading it from your account. This has new features that the PhotoKey did not have.
The latest versions of our products are fully supported and include powerful new features and major improvements, including compatibility with modern operating systems.
