Sage BI Addin Not Enabling for non Admin user in Excel 2010


I have installed Sage Intelligence and connected to Sage X3 V6.5. In the server, all reports are working.On the client system also I have installed Sage BI and its working fine in the 'Administrator' account. 

When I log on using the 'user' account on the same laptop, the Excel BI addin is not getting enabled. As BI is not fetching any data into excel. Any clues?
