Version Mismatch on Deployment

Hi,

I think I have a version mismatch problem here on deployment, but cannot figure out how to resolve it. We have two ASP.NET web apps deployed, called App1 and App2. Both use Crystal Reports. The reports display fine in a report viewer on App1 but on App2 all I get is a blank viewer.

App1 was originally developed in Visual Studio 2008 along with CR2008, incorporating CrystalDecisions.Web ver. 12.0.2000. Then it was deployed to the server, along with appropriate redistributable. It all worked fine.

App2 came along, and I switched to VS2010 and CR2010. I also converted App1 to build and run on my dev machine in VS2010 and CR2010, using CrystalDecisions.Web ver. 13.0.2000. On my dev machine, both apps run fine and report fine.

I deployed App2 to the server, along with the appropriate redistributable for CR. I did not deploy the updated App1. So now on the server, App1 is looking for ver. 12.0.2000.0 of CrystalDecisions.Web in the GAC, and App2 is looking for ver. 13.0.2000.0.

I have verified that both versions of CrystalDecisions.Web are in the GAC.

Now App1 still reports fine on the server (although there were some non-reproducible hiccups), but App2 will not display the report. The viewer comes up blank. Again, this works on my dev machine.

Any suggestions as to why App2 will not view the reports? The relevant code from the App2 web.config is listed below. The source code from the page that actually displays the report is in a followup reply, since it seems too large to put in this message.

Thanks.
