I have both LabVIEW 2012 and 2013 but MathScript RT Module can only be installed in 2012 not 2013

It can be succesfully installed on 2012 and I can't choose to install it on 2013. Why can't I install MathScript RT Module on both versions? Or did I do anything wrong?

Are you installing the  version of the module that matches the LabVIEW version?

What kind of errors do you get?

I downloaded the module from the school app website. It titled with LabVIEW2013 but it's actually for 2012 I think. I downloaded 2013 version from NI website and it works fine. Thank you for your help!
