When you deploy any PowerBuilder application or component, you should always make sure that the version and build number of the PowerBuilder runtime files on the target computer or server is the same as the version and build number of the DLLs on the development computer. Mismatched DLLs can result in unexpected errors in all applications. If the development computer is updated with a new build, PowerBuilder .NET Windows Forms applications must be rebuilt and redeployed with the new runtime files. [CR 483818]
