Hi Wang,

I believe you are on BI 4.0 version?

Also does the application work fine and you observe these errors in the logs while the application works fine?

Awaiting your response.

Thanks,

Thank you very much for your answer!, yes, I am using BI 4.0, Crystal reports 2013, where can I find the error log, and how to deal with, very much looking forward to your answer next time, I just contact this soon, thank you very much for the answer.

The viewer's any function is correct

Hi wang,

In BI 4.0 we have observed these messages being captured in case of viewing a crystal report as error messages but your application works fine.

I have the following questions

1. The error messages you pasted above, do they come when you run your code and application breaks because of the errors, or those are captured in logs and you are able to view your reports fine?

Thanks,

Prithvi

HI! Prithviraj Shekhawat, once again thank you for your answer, I can well see my report for errors, and I have a few doubts, first, "-Unable to determine installed languages" I guess this error is not in BI need to install a language pack on a 4.0 second, in my project does not seem to configure CRconfig.xml, the function has no effect, what CRconfig.xml specific role?
