Just to answer the question, this pop up is completely normal. It shouldn't affect your game in any way, it's harmless and it happens to all Windows 7 users because the theme of Windows 7 is too advanced for GTA: SA to use, so it switches to the basic one.
This doesn't apply if your problem was the second problem, which is if the game refuses to run, but I believe that there's a fix for that that I can supply if you want, but you already said that you upgraded to Windows 10 and you don't need help anymore, so there's no need.
