Unable to save file from SAP netweaver Portal

Hello,

I am facing some issues in downloading or saving any data in excel from SAP portal. Current version of my SAP Portal is NW7.4 sp07.

When I am trying to save the data into excel nothing happens. Initially i thought its a Java version problem(currently Java 7 sp65 in my system) but i tried upgrading and degrading the java version but the problem still exists.
