I have Crystal Reports XI R2 installed on a windows server 2008 R2 Enterprise server and when a when I browse to my asp.net page withe the crystal reports viewer I get the red x's for the toolbar images. The viewer and web.config entries all reference the 11.5.3700.0. When I view the source of the page the source is "../aspnet_client/system_web/2_0_50727/crystalreportviewers115". At first the crystalreportviewers115 was not in subfolder at my sites root aspnet_client folder and so I copied it there. But it still doesn't work.
What seems odd is that we I was using the embedded version from VS 2008 (10.5.3700.0) the view source of the page showed the image path as "/aspnet_client/system_web/2_0_50727/CrystalReportWebFormViewer4" and this worked fine but when I use XI R2 (11.5.3700.0) the path is "../aspnet_client/system_web/2_0_50727/crystalreportviewers115" so where and why is there ".." for the XI R2 version.
