Use JRE in base

I am using Base in LO 5.0.3.2. I am trying to create a report using report builder, but when I try to open “Create report in design view” by clicking on it nothing happens. I suspected it might be because I did not have JRE, but have found that I do have JRE 1.7 installed, so I am at my wits end. Any help appreciated.
