Oops!
I happen to find that

SOLVER
Microsoft Forms 2.0 Object Library

in VBA References in Excel can't be checked permanently,that's once I
check them in a new blank excel file,and then close that blank file(of
course I don't save it) and open another new excel file,those two
component are back in the unchecked state.

but this weird phenomenon doesn't occuered for others,I don't know how
to solve it...
