By default executables downloaded from ISL Conference Proxy (e.g. ISL Light Desk, ISL Light Client etc.) are digitally signed using our special code signing certificate (name of signer PDQ.com Corporation). This means that they should not trigger any warnings/errors (such as Microsoft SmartScreen Filter download warnings) that could be caused by unsigned executables or executables signed by code signing certificates that are no longer trusted (e.g. SHA-1).
The code signing certificate gets renewed by ISL Online regularly (every few years) and in order to get the updated certificate, you will need valid server license with Upgrades & Updates and a freshly generated license file.
Important: This applies to all customers with valid server license who have created their license file after 2015-04-16.
Important: Please make sure your license file and ISL Conference Proxy are up to date. You should create a new packet every time you extend your server license so that the resulting license file includes the latest code signing specifications and your actual license expiry date, allowing you to update your server to the latest released versions at any moment. In case you purchased server license with Upgrades & Updates for a few years, you might have to create a new license file even before your server license is near the expiration date, so that you get the latest codesign certificate.
Important: If you do not have a valid server license with Upgrades & Updates when creating a packet, the resulting license will not include the code signing functionality! In that case please extend it (direct link to our online shop) first, then proceed to create a new packet.
If your company has registered for a server license trial and would like to test the code signing functionality before purchasing, please contact us at support@islonline.com or visit our Live Chat.
If you are an advanced user and wish to use your own code signing certificate instead, please check the following topic: Using a custom code signing certificate
