I have created an ASP.NET application that provides pricing information for company sales representatives. The application utilizes a Crystal Report that has been displaying correctly for over a year until recently. I host this application on a third part hosting company. After the company updated their servers to IIS 2012, the website has failed to run the report. I was not able to get technical support from the hosting company and am working with a large international hosting company that specializes in Crystal hosting.
I have published my application to the new host and am not able to run the report as previously from the application. The report will show in the embedded crystal viewer of my application when I run the report in the Visual Studio 2010 programming environment (localhost). The crystal viewer control does not show at runtime in the ASP.NET application when the webpage is displayed from the host. No errors show on the screen or in the web site log indicating the reason for the failure.
Some things that I have tried.
I have installed the most recent version of Crystal Reports for Visual Studio (13.0.15).
I have copied the aspnet_client folder to the httpdocs folder of the web host to confirm that supporting files are present for Crystal.
I have the program compiled as an x86 program.
I have confirmed that application pool is set to 4.+ on the web host. I do not have control of “classic mode” on the new web provider that I can find.
I hope that you can point me to a resolution for this problem.
