Hi there, 

I am trying to install PowerPivot on an existing Sharepoint 2013. I've followed this guide to do so: http://msprojectmvp.blogspot.ro/2015/01/how-to-configure-and-build-powerview.html

Except i made 1 mistake, when i added the Reporint Services features (sharepoint addins) i didn't select POWERPIVOT instance. I selected by mistake the MSSQL instance. And now i have the feature installed on the wrong instance. However when i try to install it on the correct instance, the features seem like they are added but are also grayed out. And Sharepoint does not give me the SQL Reporting Services Application. I would like to avoid uninstalling and reinstalling the feature.

Is there a way to add and existing feature from one instance directly to another? Basically i want the Reporting Services Sharepoint addins that exists on the MSSQL instance to be  moved, or added to the POWERPIVOT INSTANCE.

Thanks.
