how to patch gateway

[ps0831]

According to all recommendations, we should always patch our on-premise data gateway to the current version.  What we cannot find is a description of how to obtain and apply the patches.  Our first assumption was to download the latest version and then execute on the data gateway server.  However, this results in an error message

"The on-premise data gateway installation has failed"

"It looks like you are trying to reinstall.  Please uninstall the current version first."

Does this mean that we need to install the old data gateway and install again to apply the latest patches?  How would we retain the configuration of the old installation so that it can be re-entered in the new installation?

Thank you in advance.

Hi @ps0831,

Each new on-premise data gateway is released as a standard installer package. We need to download new data gateway installer file then install it. If there is already a data gateway version installed before in this machine, there should be a Update button to update data gateway.

In your scenario, please go to Control Panel -> Programs, check if there is a on-premise data gateway already installed. You can try to uninstall it then download installer from here to install again.

If issue still persists, please share log files below:

Installer logs

%localappdata%\Temp\On-premises_data_gateway_*.log

Configuration logs

%localappdata%\Microsoft\on-premises data gateway\GatewayConfigurator*.log

Best Regards,

After restarting the server, the 'Update' button appeared with the installation.  I was then able to complete the update.

Thank you
