Yes, but the docs for SafeArrayCreateEx or SafeArrayCreateVectorEx do NOT have such a notice.

Maybe by interpreting > "SAFEARRAY(VARIANT*)" as "SAFEARRAY(VARIANT)"? An easy fix is to insert this line POINTER(VARIANT): VT_BYREF|VT_VARIANT, into the definition of the _ctype_to_vartype dictionary, at the end of the comtypes\automation.py module. This will let you import the typelib, but you will get an error if you want to call a method that uses such an argument type.
