I own a ASP.NET web project with framework 4.5. Is installed and implemented an SAP report for VS2012 Crystal Reports Developer.
Making in Local report, it works correct
For me, the webpage Developer Tools (F12 then Console tab) showed that the server was looking for root/aspnet_client/system_web/4_6_1069 folder when I had copied the files into the 4_0_30319 folder. I renamed the folder and BAM!
