It sounds like your application has references to both versions. Have you recently upgraded your project?

You need to make sure that your application is only referencing one version of CR.

Which version of Crystal Reports are you using? It looks like you have two versions installed.
no errors found in ur code....

You need to install Crystal on the server using the provided msi for the vs2008 version...

C:\Program Files\Microsoft SDKs\Windows\v6.0A\Bootstrapper\Packages\CrystalReports10_5\CRRedist2008_x86.msi

Installing this will add the required CR assemblies to the GAC. You should not add them to your app's bin folder.

Just go in to the web.config file and check for the crystal report refrence is added properly if there is a 2 different version you find there then just remove one version refrence because at a time to run the report you requried only one refrence
