Failed to load database information Error After publishing the code IN IIS

Hi,

We are migrating our all the reports from the old version of Crystal report to new CR2016. I have done the development phase of this application. At the time it shows "Failed to load database information" error for resolving that I have installed the 32 bit oracle and the issue is resolved. Now I have hosted the same application in the IIS of the same machine. But now it showing the same error message for those reports that have the error before installing the 32 bit oracle client. At the time of publishing I have I have enabled the 32bit application to "False". After that error is changed to "The type initializer for 'CrystalDecisions.CrystalReports.Engine.ReportDocument' threw an exception" for all the reports. Please suggest a way to resolve this issue.
