The Game is 7 years old and was written for the OS you mentioned and is therefore listed as compatible for this operating systems.
That doesn't mean the game will not run on Windows 8.1 or Windows 10, as a matter of fact it does run most of the time without any problems on this operating systems.
It is not working for me. I have tried to open it and just show work in background sign on the mouse pointer and shows the normal pointer and the game doesn't start, I have tried it many times the same thing happen.
Please create a DxDiag, also go to your Reliability monitor (Press the windows key and "R" at the same time and copy or type "perfmon /rel" (without the quotes) in > ENTER and look if it has ME2 entries.
If yes double click at the last one, copy it to the clipboard, (Bottom left corner) save it to a text file and load it up together with the DxDiag. You can do that with the "choose file" button at the bottom right corner of the reply window.
pls help..... the file?
Close Origin completely.
Go to your "Documents\BioWare\Mass Effect 2" folder and move the "Save" folder to your Desktop. > Test.
