Yes it does.Does MusiCAD 3 run on Windows 7?
Like other pre-version-7 programs, the changed file locations and the new library storage in Windows 7 will not be handled by MusiCAD in Windows-7 style, but in Window-XP compatible style. However, most users will never notice the difference.
To determine whether or not MusiCAD 3 will fit your bill is easy: just download and try.
