Hi,
I am using Crystal Reports XI R2 to design my reports but using version 13 of the files in my project (vs2010). Everything worked on Server 2008 but on Server 2012 I get error 404. At first I thought it was because I was doing a window.open command to open a new web window. I created an empty form and the popped up fine. It only seems to be happening on forms which create a report and show it as a PDF.
If you need anymore information please ask, sorry if it's a bit vague but so is error 404.
Regards,
Roger
