Hi,
 
I developed by web app using vs2005. The report were created using CR bundled to VS2005. When i deployed by app in our production server it works fine. But one day, the reports returns an error. when i tried to trace the cause of the error., it says that the COM used by CR was not loaded. So, I re-installed the app. It work fine again.
 
I encountered again the same problem.
 
Is there a way to resolve this kind of problem w/o reinstalling the application.
 
Why is it that suddenly,  VS2005 can't load the COM of CR? but if you check the file in the server, the file exists.
 
 
Thank you.

That's weird. Is it possible another app is conflicting with the DLLs installed? CR is not 100% managed code and there are COM DLLs installed. Maybe there are CR .NET 2003 apps instaled also?

I find it wierd also.
 
yes, it is possible since it is a production server most of the applications are installed there. The web applications were developed using different programming langage.

If you want to get into the nitty-gritty, I wrote a utility that outputs all your CR files and their version number to an XML file. You can run this when your app works and when it doesn't work and compare the two files against each to see what is different. I have a link to it on my home page (Business Objects has it in their support site).
