Excel Solver adds-in

Hello, I'm currently working with Excel solver for optimazation. Is it possible to change some setting in it? Because here is the case, when I calculate (GRG Non-linear) in other computers, I got the value of langrangian multiplier in negative value, how ever when I make it in my laptop (with the same exact data), the value is the same only it's on positive value. I suspect there is some setting that caused that difference. Please help me, thank you.
