Nx Witness User Manual

Compatibility mode lets you launch a compatible version of the client application in order to connect to a Server running a different version of Nx Witness. The Client downloads another version of itself to match the Server version using the same method as an auto-update.

This would be necessary, for instance, when Nx Witness is installed at multiple sites (factory, store, warehouse, etc.) and only one installation has been updated to the current version. In that particular case, the System will have different versions and one Desktop Client should connect to another System (i.e. Client at a store connects to the System in a factory). Systems of different versions are highlighted in red in the log in dialog and in yellow on the Welcome Screen.

When a Desktop Client is connected to a Server, all component versions are checked and a warning is displayed prompting to restart in compatibility mode if the component versions differ from one another. Click Restart to connect to the Server in Compabilitiy Mode.

In some instances, it may be necessary to download additional files for the compatibility pack. Once the download is complete, the client should be restarted.

IMPORTANT: The best practice is to have the same product version installed on all System components. If some of the components (Server or Client) in a multi-Server System have different versions installed there may be operational issues.
