Hello all. I'm new to this forum and I apologize if this question appears in the wrong section.
I have seen variations of this problem discussed but none are quite like this, and none of the responses to date have helped. I have a Crystal Report viewer web app developed in VS2010 with VB.NET. This application worked fine on a Windows 2003 Server system for many years. I've recently moved it over to a new WinServ2012 R2 machine as 2003 is no longer supported by Microsoft or our ITS department.
On the new server, the app runs fine, displaying a menu of file names, and opening a given report in a Crystal Reports viewer in the browser when clicked. However, if a user clicks on "Go to Next Page" or any other controls in the CR Viewer toolbar, the error "Invalid report file path" is displayed in a pop-up. It is therefore impossible to view beyond the first page.
It's interesting that the viewer is able to load the report at all. What's more interesting is, I can copy this exact same code to the old server, and it will run fine, displaying reports from the share on the new server, and paging through them without error.
Can anyone help me diagnose this issue? This is a fairly urgent question as we are on a timeline to phase out the old server within a matter of days. I can attach code samples and screenshots as needed.
