The SilentPrint application is installed and the Service Utility is then added. Although the service starts no processing takes place unless the application is started.
If you encounter a situation where the SilentPrint service has been installed but no processing takes place until an instance of the application has been started this is likely to be due to the location of the SilentPrint application.
If you plan to use the Service then the application must be installed to the default path the installer provides during install e.g. C:\Program Files\Silentprint. If you install the application to a different path then install the Service this will cause problems.
Unfortunately we cannot force the default path upon the user when installing the application. The application itself can be run from a non-default path so we need to allow for the path to be changed. A problem should only arise if the Service is then added to the configuration.
