What do you mean by "does not work"?
Does it not start at all or when you double click on a file it always opens in MuS 4?
MuS 3 can not open files saved with MuS 4 directly, there comes an error message.
And if MuS 4 was installed last, then the operating system uses MuS 4 to open with the double-click.
Just drag a MuS 3 file into the window of MuS 3.

As explained, MS4 has become the default application to open files with a suffix .mscz.

In Windows 10, you can also get around this by right-click on the filename of your MS3 score, then:
Open with > Choose another app > More apps > scroll down to select MuseScore 3 > click OK
