Update using a script

In the latest versions, there is another way to update the server – using the PowerShell script update.ps1, which is located in the directory with the server (C:/Hideez/HES/update.ps1). This script has the following command line parameters:

-service - Name of IIS site. Default HES

-url - URL to download the update file. The default, URL will be taken from

But you can override these parameters. For example, to update HES offline, from the file "", located in the C:/Updates directory, you can run the script in PowerShell, as follows:

update.ps1 -url file://C:/Updates/
