Recently, I discovered why the succeeding versions of Crystal Reports .NET web applications on the same machine work without conflict and the advantages of verifying the Viewers’ Virtual Directory for web applications.

Crystal Reports heavily relies on a virtual directory to access viewers for display. As evident from following table, virtual directory and its underlying file path are unique for each version of Crystal Reports,  that is the reason why succeeding versions work.

While developing the web application or web site it is always good to verify that the Viewers’ Virtual Directory has been correctly installed on the development, and deployment, web servers; as it may help you save some time on troubleshooting the unfamiliar issues.

While creating the table, I have assumed that the Crystal Reports has been installed on the machine with the default settings. Developer’s Guide can be checked for more reading (Crystal Reports XI R2 and Crystal Reports 2008).
