A Microsoft Dynamics CRM Server component is using the same account as the instance of SQL Server Reporting Services

Hi,

I am upgrading CRM 2013 to CRM 2015.  I uninstalled Microsoft Dynamics CRM SQL Reporting Extension 2013.

Microsoft Dynamics CRM and Microsoft Dynamics CRM SQL Reporting Extension on different servers.   

I could install Microsoft Dynamics CRM SQL Reporting Extension 2013 without any error but I got below error when I install Microsoft Dynamics CRM SQL Reporting Extension 2015. Kindly help me to solve this issue.
