Integrating SharePoint 2013 with ProjectWise V8i

Hello,

I have been stuck with the above task for over a week now and would be grateful for any help I can get from on here. I am stuck trying to install the "SharePoint Search Integration" module of the "ProjectWise Web Server and Web View Server" server install. There is a big red sign by the side which is stopping me from  installing the feature on my server. I have configured my SharePoint Search correctly as required. 

I have also downloaded and installed the "ProjectWise V8i WebServer Module for SharePoint 2013"

Is there anything else I'm missing? Please help!
