Hey,

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....

hi

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
