Do not chase missing dlls. Depending on which version of the SDK/runtime you used in the development of your WPF application, you'll need to install the runtime on your target machine. They can be found at the SAP site. Or for the version 13 downloads named CRforVS_redist_install_XXX, directly from here (version 13 32bit) and here (version 13 64bit)
