Minimum System Requirements
Please see the FireDaemon Zero Compatibility and Support Matrix.
Important: Review the Deployment Matrix
Before deploying FireDaemon Zero on any system, please refer to the FireDaemon Zero and ZeroInput Deployment Matrix for important information about compatibility and minimum system requirements. You will have to deploy FireDaemon ZeroInput on newer versions of Windows. Additionally, Windows 10 and Windows 11 may be VBS / HVCI enabled which will cause FireDaemon ZeroInput to not work properly. This article describes how to disable VBS / HVCI.

FireDaemon Zero 3 New Features
|Microsoft ceased delivering 32-bit native operating systems in 2020. Hence, FireDaemon Zero 3 is now only offered as a 64-bit product.
|Hardware-based code signing
|All FireDaemon software products have been digitally signed for several years. Earlier installers and binaries were signing with SHA1 and SHA256 2048-bit digests. Zero 3 implements hardware-based SHA256 4096-bit Extended Validation (EV) code signing. SHA1 has been dropped. This adheres to industry best practices and provides two levels of trust:
|Zero Input Compatibility
|FireDaemon Zero 3 works with FireDaemon ZeroInput to give extended error reporting via the FDUI0CLI query --fdui0input-state command line option. FireDaemon Zero 3 will also warn you if you have not installed FireDaemon ZeroInput or the driver is not running correctly.
|Command Line Binary Name Changes
|FDUI0Control.com and FDUI0Control.exe have been renamed FDUI0CLI.com and FDUI0CLI.exe for consistency with other FireDaemon products.
|Task Tray Service Names
|The name of the FireDaemon Pro service name is listed in the FireDaemon Zero Task Tray that runs on Session 0
|Enable Legacy Console
|Legacy Console Mode can be enabled for the Localsystem user via Options -> Quirks. This makes interactive console-based applications running under FireDaemon Pro control visible on Session 0 when using 3rd-party remote control products such as TeamViewer
|Context Menu Changes
|The "Documentation" option has been removed from the Session 0 context menu as this requires a browser that works sanely on Session 0. A "Screen Refresh" option has been added to the Session 0 context menu to allow you to force the refresh / redraw of GUI components on Session 0.
|We always shipped the most recent Microsoft Visual C++ Runtime inside the installer which was installed as a pre-requisite. This dependency has been removed and FireDaemon Zero 3 now uses the Universal C++ Runtime which is pre-installed with the operating system and maintained via Windows Update. This results in the installer being significantly smaller.
|FireDaemon Zero 2 and earlier installers were built using InstallShield. InstallShield does not support the detection and deployment of the Microsoft Visual Studio Runtime (MSVCRT) particularly well, forcing reboots in the event of earlier versions of the MSVCRT being present on your computer system. We have replaced the InstallShield MSI installer with an Advanced Installer MSI installer package that correctly handles MSVCRT deployments and upgrades.
|The need to supply a Software Bill of Materials (SBoM) is now often mandatory for various industries as part of a supply chain software audit. FireDaemon Zero 3 includes an SBoM. It can be found in the About dialog.
|Software Assurance and Priority Technical Support Subscription
|FireDaemon Zero 2 offered two subscriptions to customers. A Software Assurance subscription and a Priority Technical Support subscription. This often caused confusion regarding software upgrades and support entitlements. To resolve this we now have a single unified Software Assurance and Priority Technical Support subscription. It costs roughly the same as both previous subscriptions. We feel this will be easier to manage and simpler to understand from an upgrade entitlement, software procurement, and support perspective moving forward.

FireDaemon Zero 3 Documentation
We are currently in the process of updating the FireDaemon Zero 3 documentation. The FireDaemon Zero 3 OEM configuration and installation guide is available here.
Before Upgrading To FireDaemon Zero 3
Before you consider upgrading to FireDaemon Zero 2, please ensure you have completed the following pre-flight checks:
Step 1. Check Compatibility
- Check the FireDaemon Zero and ZeroInput Compatibility Deployment Matrix to ensure your system is supported.
Step 2. Backup
- Ensure you backup and/or snapshot your machine.
Step 3. Get New License Keys
- Your FireDaemon Zero 2 or earlier license key will not work with FireDaemon Zero 3.
- If you have an active Software Assurance subscription you can upgrade to FireDaemon Zero 3 or FireDaemon Zero OEM 3 for free. Please contact us to obtain your new license keys or link to download FireDaemon Zero 3 OEM.
- Otherwise, if you have purchased an earlier version of FireDaemon Zero, you will need to purchase a FireDaemon Zero upgrade license key.
Step 3. Check Your Upgrade Path
- If you have FireDaemon Session 0 Viewer 1 installed, this product will be removed and replaced with FireDaemon Zero 3.
- If you currently have Zero 2 installed, your version will be upgraded to FireDaemon Zero 3.
Step 4. Prepare for the Upgrade
- If you have applied your FireDaemon Zero 2 license key, then your license key will no longer be valid. Please apply your FireDaemon Zero 3 license key once the upgrade is complete.
Interactive Services Detection Service has been removed from Windows 10, 11, and Server 2019, 2022
Microsoft removed the Interactive Services Detection Service entirely on Windows 10 1803 or later versions, Windows 11, Server 2019, and Server 2022. Hence, it's no longer possible to switch to Session 0 on those OS versions via the Interactive Services Detection Service (UI0Detect). If you are running Windows 10 1709 or earlier versions of Windows then Session 0 access still works as normal. If you have FireDaemon Zero installed and you upgraded to Windows 10 1803, the Interactive Service Detection Service will be preserved, however, when you switch desktop, you will switch to a blank screen. You will need to deploy our ZeroInput driver to resolve this issue. Ensure you review the FireDaemon Zero + ZeroInput Compatibility Deployment Matrix before deploying FireDaemon Zero.
Forced re-login when returning from Session 0 on Windows 10 1809 and Server 2019 1809
If you RDP into Windows 10 1809 or Server 2019 1809 or later versions and switch desktop to Session 0 then attempt to switch back to your logged-in session - you will always be returned to the Windows login screen. We have no fix or workaround for this. Note that you do not see this behaviour if you are logged directly into the Windows 10 1809 or Windows Server 2019 1809 console.
No Access to Session 0 via RDP on Windows 10 1903 or later, Windows 11, or Server 2022
Switching to Session 0 on Windows 10 1903 or later, Windows 11, or Server 2022 over RDP no longer works. It would appear Microsoft is now actively blocking the contents of the Session 0 desktop from being rendered in the RDP session and/or dropping the RDP session entirely. If you try switching to Session 0 your RDP session will hang, you will have to forcibly disconnect and then reconnect to your computer. The only workarounds that we know of are:
- Login to the physical console session of your computer directly (e.g. via physical keyboard and mouse, via hardware-based computer gateways such as Dell iDRAC or HP ILO, or via virtual machine console offered by VMware vSphere or equivalent).
- Abandon Microsoft RDP entirely and try using an alternate remote control product instead such as TightVNC, TeamViewer, or TSplus. Your mileage may vary depending on the remote control tool you choose and the particular version of Windows you use. Ensure you test thoroughly.
RDP session freeze when switching to Session 0 on the console session on Server 2012 R2, 2016, 2019, 2022
If you connect to the physical console of your Windows Server (i.e. the desktop to which the keyboard and mouse are connected) and then switch desktop to Session 0, all existing RDP sessions will freeze until you return from Session 0. From our investigations, this appears to be due to an unresolvable issue in the terminpt.sys driver that is used by the "Remote Desktop Keyboard Device" and "Remote Desktop Mouse Device". There's no fix or workaround.
Interactive console applications running on Session 0 on Server 2022 may not be visible when using TeamViewer
If you TeamViewer to your computer and switch desktop to Session 0 console applications (e.g. cmd.exe, powershell.exe) running as the user LocalSystem will not be displayed on the Session 0 desktop. To resolve this you need to enable legacy console for the LocalSystem user or a user with local machine administrative privileges and then run the FireDaemon Pro service as that user.
Enable Legacy Console for LocalSystem
You can also enable legacy console for LocalSystem via the FireDaemon Zero Options dialog -> Quirks tab. Alternatively, you can enable legacy console for the LocalSystem user by creating the following registry key. Ensure you restart your machine for this change to take effect.
Enable Legacy Console for Other Administrative Users
Note that for FireDaemon Pro services to be visible on Session 0 they must be run as a user with local administrative or domain administrative privileges. To enable legacy console for that user:
- Login to a computer as the specific user with administrative rights
- Start cmd.exe
- From the cmd.exe context menu choose Properties
- Check "Use legacy console" then click OK
- Then change the logon credentials of your FireDaemon Pro service to those of the user you just logged in as (i.e. a local or domain administrator). To do that:
- Start FireDaemon Pro GUI
- Edit the FireDaemon Pro Service
- Click on Settings tab
- Change the Logon Account to .\Administrator or another local or domain administrator account and set the Password
- Restart the FireDaemon Pro service.
