+### .NET 8 runtimes
+
+Webhook Server is published as framework-dependent (so the installer stays small) and needs two .NET 8 runtimes on the target machine:
+
+| Runtime | Used by | Auto-installed by setup |
+|---|---|---|
+| ASP.NET Core 8 Runtime (`Microsoft.AspNetCore.App` 8.x) | the Service / Kestrel | Yes |
+| .NET Desktop Runtime 8 (`Microsoft.WindowsDesktop.App` 8.x) | the WPF GUI | Yes |
+
+A clean Windows Server install has neither. The installer detects what's missing and downloads + installs each one silently before copying our files. If the machine has no internet access, install them manually first:
+
+- ASP.NET Core 8 Runtime — <https://aka.ms/dotnet/8.0/aspnetcore-runtime-win-x64.exe>
+- .NET Desktop Runtime 8 — <https://aka.ms/dotnet/8.0/windowsdesktop-runtime-win-x64.exe>
+
+Run each with `/install /quiet /norestart` for unattended installs, or just double-click. A reboot is rarely required.
+
+To check what's already installed:
+
+```powershell
+dotnet --list-runtimes
+# expect to see Microsoft.AspNetCore.App 8.x.y and Microsoft.WindowsDesktop.App 8.x.y
+```

+### Service won't start after install / GUI says "Disconnected" with no obvious error
+
+If `Get-Service WebhookServer` shows it stopped and `Start-Service WebhookServer` fails, or the GUI itself won't even launch, you're probably missing a .NET 8 runtime. The v0.1.4+ installer auto-fetches them, but a clean Windows Server box might still hit this if the install was offline or used an older installer.
+
+Check what's installed:
+
+```powershell
+dotnet --list-runtimes
+```
+
+You need both:
+
+- `Microsoft.AspNetCore.App 8.x.y` — for the Service
+- `Microsoft.WindowsDesktop.App 8.x.y` — for the GUI
+
+If either is missing, install from:
+
+- ASP.NET Core 8 Runtime — <https://aka.ms/dotnet/8.0/aspnetcore-runtime-win-x64.exe>
+- .NET Desktop Runtime 8 — <https://aka.ms/dotnet/8.0/windowsdesktop-runtime-win-x64.exe>

+Re-run with `/install /quiet /norestart` for unattended installs. Then `Start-Service WebhookServer`.
