Your game is almost 14 years old now, and Windows 10's version of a "compatability" to WindowsXP is inadequate to the task. When Windows 10 was relatively new, and a digital version of Simcity4 was on hand at Origin, that one sometimes worked for people, but that was a couple of years ago. I have no idea at all whether there is any way to get a digital version any more.
You may want to discuss the possibility with a game Adviser at Help Center.
