More Information:

This error can occur when the web.config file that ReCrystallize Pro creates is duplicated in a lower level folder. 

The web.config file should ideally be included only in the highest level directory of an application and should not be duplicated subdirectories.  Any duplicated copies of the web.config file in the lower level folders should be deleted.

About the web.config file created for ASP.NET

ReCrystallize Pro creates a web.config file along with each set of ASP.NET web pages.  The web.config file includes the minimal configuration settings necessary for the web application to display your reports. The web.config file is not unique for each report; it is common to all report web pages that use the same Crystal Reports version.

The recommended best practice is to place one copy of the web.config file at the root of the web site or at the top of the folder structure within the web site that houses the ReCrystallize Pro web pages and reports.  It is permissible to include  copies of the web.config file in multiple folders that are at the same level within the web site.  However, the web.config file must not be included at different levels within nested folders or an error will result.

 Example of recommended best practice placement of the web.config file:

 

c:\inetpub\wwwroot\reports

      web.config

       c:\inetpub\wwwroot\reports\financials

            financialreport-parameters.aspx

            financialreport.aspx

            financialreport.aspx.vb

            financialreport.rpt

      c:\inetpub\wwwroot\reports\sales

            salesreport-parameters.aspx

            salesreport.aspx

            salesreport.aspx.vb

            salesreport.rpt

            c:\inetpub\wwwroot\reports\salesbyregion

                  salesreportbyregion-parameters.aspx

                  salesreportbyregion.aspx

                  salesreportbyregion.aspx.vb

                  salesreportbyregion.rpt

       c:\inetpub\wwwroot\reports\hr

            hrreport-parameters.aspx

            hrreport.aspx

            hrreport.aspx.vb

            hrreport.rpt
