Hi,

I'm getting below error message.

"Unknown database connector error. Error in xxxx.rpt."

I'm using crystal decisions 11.5 and database oracle 11g. VS 2012. While debugging it shows inner exception as "crystaldecisions.crystalreports.engine.datasourceexception". Please help me to resolve this issue.

Thank you.

Crystal Reports 11.5 did not support Oracle 11g and is out of support (has been for a few years now).

Additionally CR 11.5 is not supported with VS 2012.

For designing report, you will have to upgrade to the currently shipping version of CR - SAP Crystal Reports 2013. Eval is available from here:

For VS 2012 apps, you will have to download the SAP Crystal Reports, Developer Version for Visual Studio .NET

Hi Ludek,

Thank you for your reply.

In my application crystal report dlls used to display existing .rpt file, not  for designing new report.  So do I need to use the above mentioned CR - SAP Crystal Reports 2013?

Does crystal reports 11.5 support Oracle 12c?

Also with 12c database I'm getting same error message as mentioned above.

Well, CR XI R2 did not support Oracle 11g, so 12c would be even more not supported(?).

In your VS 2010 app, use the CRVS I linked to in my previous post. On your dev computer, run the install exe, on runtime computers, use the MSI, MSM or CLickOnce.
