I bought Sims2 and the picture quality is worse than the old Sims2.

I purchased Sims 2 and was able to start it, but the resolution was terrible, so I checked and found that I had created an old “EA Games” folder and called it “The Sims 2 Legacy” folder.
I had the old saved data, so I renamed it to “The Sims 2” in “Electronic Arts” as the official version says, but it only loads the “EA Games” folder.
I had no choice but to move the saved data to “The Sims 2 Legacy” in “EA Games”, but the image quality is very poor and blurry compared to the Sims 2 I used to play.
The window size is still large and I can't open multiple windows, probably because it's the old “EA Games” version.
I thought it was the “EA Games” folder, so I discarded this folder, but every time I start Sims2, it creates an “EA Games” folder and a “The Sims 2 Legacy” folder and won't load “The Sims 2” from “Electronic Arts”.
How can I play Sims 2 with the old beautiful Sims 2 quality level and multiple windows open?
Please help.
Does anyone else have a similar situation?
