.Net Crystal reports migration from VS2010 to VS2013 Error

Am migrating a .Net application from VS2010 to VS2013. Crystal reports are used in this application. After the migration, when the reports are run through the application am getting an error as bobj undefined. Please help me what has to be done to resolve this error. I have tried all solutions that is given in internet but nothing seems working out.


  • Here is the error screenshot:

That error is caused by versioning issue in Crystal Reports. after migrating Crystal Reports mostly failed to upgrade. check your Crystal report version.

The crystal report error “0x800a1391 - JavaScript runtime error: ‘bobj’ is undefined”, I think is caused by a messed up files versioning. In other words, you have files from different versions of Crystal Reports, which explains why the error happened after upgrading your visual studio project from 2010 to 2013.

I suggest that you try to update your Crystal Report plugin.
If that didn’t work; you may try also uninstalling the older version of Crystal Report if there are multiple versions on the same machine, only keep the latest version.

hope that helps.
