what did you install?
I don't see a steam library file, and from the actual steam library when I right click se nothing like that shows up...
I installed the auto detector that you can find on the main page of AMDs website if you just scroll down to the bottom of the page, and I have the "Lenovo Ideacentre AIO 520-24AST 23.8-Inch All-in-One Desktop Computer (AMD A12-9720P 2.7GHz, 8GB RAM, 1TB 7200RPM HDD, Radeon R7, 10-Point Touchscreen, Windows 10 Home 64-Bit) F0D3000EUS", and the title here should say everything you would want to know.
No problem. By the way you have the exact same processor than Propulsion Disk up here, so you could check and update your graphic drivers from that same link, every now and then. Maybe some driver update could solve specific issues you encountered with SE 0990, judging by the release notes they do that often.
