The stcd.exe is the main executable file for the Memorex exPressit Label application. If that file is causing errors, then I recommend to completely uninstall the application. You can use Revo Uninstaller. This application wipes everything there is about an application (tmp files, registry entries, obsolete files, settings, directories, etc.)
Once you have wiped the software completely, proceed to its reinstall procedure and it should work.
