i am trying to install powerpivot for sharepoint 2013. I have installed it multiple times before, usually without any problems. The config tool is giving me this error when trying to deploy to powerpivotfarm.wsp to all servers:
Error: Cannot add the specified assembly to the global assembly cache: Microsoft.AnalysisServices.SPAddin.dll
anyone ever see this issue before? All windows server 2012, and sql 2012 spi cu 4 environment.
Thank you
