I use Windows 10 Home 64-bit which i have fully updated and yet i keep getting a message every time i start up RSI app saying "You are trying to run the game on an unsupported Windows OS. This will likely result in undefined behaviour". The Windows Home was bought legitimately and installed by the PC company that built it, it is fully updated and working fine so am puzzled why i keep getting this message. Also the last update it refused to update at all saying "You need to use Windows 7 or above". Please could someone offer some advice on this. Thank you very much My system is CPU Amd ryzen 5 Motherboard gigabyte X570 gaming X am4 Graphics nivida geforce gtx 1660 Storage samsung ssd 860 evo 500gb windows 10 home 64-bit
