How to use SUpdate to Upgrade


The primary objective of SUpdate utility is to update a client’s computer without the need to download the larger install file. The SUpdate downloads a file that is typically about 50mb. The full install is usually around 280mb.


The utility for updating can be found in the Sunlync installation folder. Traditionally, the install path for SunLync is: C:\Program Files\SunLync (32-Bit) or C:\Program Files (x86)\SunLync (64-Bit).

When in the SunLync folder, locate the icon named ‘supdate.exe’

SUpdate Icon

As per any program, double click on the icon to run it.

Please note, is is best that this is run whilst logged on as an administrator account to the Windows workstation.

When opened, you will be presented with the following screen:

Check for Updates

The first option you can see if ‘Check for Updates’. Clicking this will start the patch process for the local workstation.

You will be prompted to confirm you want to patch to the latest version:

Once the update process has started, you will see a ‘Connected’ message in the message box and the utility will start downloading and running the patch files.

Once the update has completed, you will be notified.

NOTE: If you are using Windows Home and are running the SUpdate utility, all the SunLync applications need to be closed prior to updating to ensure the patch is successful


With V6.0.3.20 of Sunlync, the SUpdate utility now has the option to use different mirror sites to download the patch from.  Also, it is possible to use the clients own FTP server and account details if they want to update using a patch of their choice rather than the latest one offered by Sunlync.

Server connections

Server 1 is the default server for retrieving the latest patch from SunLync – using this server will not prompt the user for log on credentials.

Server 2 is a mirror sites that will also host the latest patch from SunLync – again, using this server will not prompt the user for log on credentials.
