Crystal report viewer does not showing reports in asp.net, after updating version from 4.0 to 4.5

Crystal report viewer was working fine before upgrading .Net version to 4.5 . When I updated the version, I got surprised with a blank page, there was nothing at the place of Report Viewer rather then a blank page. I tried to investigate using the Inspect Element developer tool but there was not too much information that could help me.

I googled , but all the answers were outdated.

  1. what was the error

Loading failed for the <script> with source “http://localhost:52583/aspnet_client/system_web/4_0_30319/crystalreportviewers13/js/crviewer/crv.js”.

ReferenceError: bobj is not defined

The problem was that I was missing the viewer engine files. I copied all files from

C:\inetpub\wwwroot\aspnet_client

to root of the project

Crystal Reports

No need to make any changes into the config file. If you have added businessobject tag into the web.config then please remove it.

All Done.
