Hi Jon, Can you please explain why VARIANT_ValidateType rejects for instance VT_SAFEARRAY variants (and more) with DISP_E_BADVARTYPE? Why does it handle the whole range VT_HRESULT - VT_CF as invalid (except VT_RECORD) ? We got one InstallShield regression from this patch (where it wants to clear a VT_SAFEARRAY I think). Ciao, Marcus
