Hi Trevor,
Yes I tried.. but the application is still not working..
It Still seems that the reporting services is running in NATIVE MODE  and not in SharePoint Intigration Mode.
See the PowerShell - Messages below :
PS C:\Users\Administrator> Install-SPRSService
PS C:\Users\Administrator> Install-SPRSService
PS C:\Users\Administrator> Install-SPRSServiceProxy
PS C:\Users\Administrator> get-spserviceinstance -all |where {$_.TypeName -like
"SQL Server Reporting*"} | Start-SPServiceInstance
WARNING: 'SQL Server Reporting Services Service' is already started on server
'APINNOIGRECREP1'
PS C:\Users\Administrator>
The service is already running..
While accessing the Reporting services configuration - and connect to default instance - it displays the Mode Native not the sharepoint..
I already installed the Add-on of sharepoint but still same issue..
If I remove the Native feature from My SQL server setup. then the reporting service doesn't connect and show the default instance.. Pls help on urgent basis.
