Issues Fixed


Known Issues

Neverfail Replicator does not permit the installation of Neverfail AM(X)s and as such, during installation the following behaviors may be seen depending on configuration of the server at install time:

  1. Applications installed on the Primary server in the default Program Files location will be available on the Secondary server after the restore to the Secondary server.
  2. Applications installed on the Primary server in a location other than the default Program Files location will have registry configuration entries, in particular those for application services, but the service executables will not be available thereby causing errors to be logged.

Service states will be set to automatic on both sides after the restore and in the case of configuration (1) above, services will start on both servers. In the case of configuration (2) above, errors will occur.
