Oh no you, you got the Could not load type ‘Microsoft.AnalysisServices.SharePoint.Integration.ReportGalleryView’ error!!! What to do now? Why did you get it? How to fix it? All these questions are now answered!
PowerPivot is a wonderful tool with a lot of power to enable
self-service BI in many organizations. There is a fine line between
having users create PowerPivot reports and building an enterprise
solution in something like SSAS. One of the things that blurs that line
is sharing PowerPivot reports, sure you could email the files back and
forth, but your exchange administrator will probably hate you after
sending a couple hundred megabyte file a few times. Luckily there is a
scalable solution between personal and corporate BI: Team BI. This
involves sending the PowerPivot files to a SharePoint site and letting
the server do all the lifting of the data processing in the background.
Enough about that and on to the real point of this post.
You have PowerPivot all installed and configured; let me first say
congrats, that is no small task. You’re very excited to go add a new
PowerPivot application to the library when you click on the link and are
greeted with a lovely error message (shown above) that reads Could not load type ‘Microsoft.AnalysisServices.SharePoint.Integration.ReportGalleryView’. This is not what you were planning on seeing, am I correct? Didn’t think so. How do we fix this and why is it happening?
Why it happens: This particular library type needs
an ASP.Net control which can’t be found because the code for it is in a
dll that is missing. It is likely occurring because
powerpivotwebapp.wsp has not been deployed to the particular Web
Application where the site in question is located.
How to fix it: Luckily the fix isn’t too difficult,
although it does require that you are an administrator since we need to
do some work in Central Administration. See below for the steps.
