How do I - Install PowerPivot into an EXISTING SharePoint 2010 farm
This one was a BEAR to work through. There’s not much out there for it and everywhere I turned it seems everyone else was either having the same problem OR suggestion we “start with a clean install”. Nice suggestion that last one. Almost like… try rebooting the computer… but I digress. So hopefully this guide will help some other poor soul save some time when they run into the same issue.
-
Due to a farm admin error during PowerPivot install that incorrectly claims that the current user is NOT a Farm Administrator, you’ll need to logon to your SharePoint server, using the SharePoint Admin Service account credentials.
-
Startup the SQL Server 2008 R2 installer in Admin mode:
-
Browse to the CD folder of the install media.
-
Right click “Setup.exe”.
