parallel studio XE Cluster edition installation problem

Hi,

I was trying to install the parallel studio xe cluster edition for windows in my computer (I have the student software license for Fortran). But there is an error says"package signature verification failed". I have tried 2017,2016,and 2015 edition of this package but they have the same problem with the signature.

When I open went into the digital signatures in the Properties it says "the certificate is not valid for the requested usage".

Can anyone help me with that?

Many thanks
