I've created a silverlight webpart using visual studio 2012 in sharepoint 2013. The xap file has been deployed to /SiteAssets/MySilverlightProject/SilverlightWebPart1/silverlightControl.xap Now, it works fine for site collection administrator but for normal users I receive following errror:
Could not download silverlight application.
So, I guess it should be a permission problem. If I'm right then I would need to know what permissions does a particular user need to be able to view a silverlight webpart?
