Fix: WinCC Viewer RT "Download Failed" and Connection Errors
If you are trying to deploy a WinCC Viewer RT (WebNavigator client) and hitting a "Download Failed" or "No connection to server" wall, you aren't alone. These issues usually stem from mismatched network settings, missing Windows components, or corrupted local project files.
Below is a troubleshooting guide to help you fix these common download and connectivity issues for WinCC Runtime Professional and Unified. 1. Fix SIMATIC Shell Configuration
One of the most frequent causes of a "Station not obtainable" or download failure is a misconfigured SIMATIC Shell.
Identify Adapter: Open "This PC" and find the SIMATIC Shell folder. Right-click it and select Properties.
Select Network: Ensure the correct network adapter (the one connecting your ES and OS/Client) is selected.
Avoid Migration Mode: Ensure "Encryption" or "Migration Mode" is disabled unless specifically required for your security architecture. 2. Verify Windows Feature Prerequisites
If your WinCC Viewer RT or Unified Runtime fails to initialize, it may be due to missing Internet Information Services (IIS) features.
Go to Control Panel > Programs and Features > Turn Windows features on or off.
Enable ASP.NET 4.5 or higher under World Wide Web Services > Application Development Features. Ensure .NET Framework 3.5 and 4.8 are active. 3. Clear Corrupted Runtime Data
Sometimes the project files on the target machine become corrupted, preventing a successful download or start.
Delete IM Folder: On your engineering station, find your project folder, backup the IM folder, then delete the original.
Full Rebuild: Perform a "Software (rebuild all)" compile before attempting the download again.
Reset Temp Files: Reset temporary HMI files in the project to clear any cached errors. 4. Fix "No Connection to Server" Errors

Troubleshooting a failing download to WinCC Viewer RT can be a headache, especially when your remote SCADA monitoring depends on it. Whether you're seeing a "Failed to create empty document" error or the system simply won't connect, this guide will walk you through the most effective fixes. Fixing WinCC Viewer RT Connection & Download Failures
When WinCC Viewer RT stops working, the issue is often tied to corrupted configuration files, user permissions, or network settings. Use the following steps to resolve these common bottlenecks. 1. Clear the Configuration Cache
One of the most frequent causes of a failed startup is a corrupted .xml configuration file. Deleting this file forces the viewer to regenerate a clean configuration upon its next launch.
Locate the file: Navigate to the following path on the client PC:C:\Users\
Action: Find the file named WinCCViewerRT.xml and delete or rename it.
Result: Restart the application; it will prompt you for fresh server details, potentially clearing any "Failed to create empty document" errors. 2. Run as Administrator
If the viewer only works for some users or failed to download the initial WebNavigator plugins, try launching it with elevated privileges.
Right-click WinCCViewerRT.exe in your installation directory (typically ...\SIEMENS\WINCC\WebNavigator\Client\bin).
Select Run as administrator. If this fixes the issue, consider adjusting the user's permanent Windows profile permissions or recreating the profile if the problem persists for specific users. 3. Verify Simatic Shell & Remote Connections
If you are trying to access SCADA from a remote PC or via VPN, the "Allow remote connection" setting is a common culprit.
On the Server PC, open Simatic Shell (usually found in Windows Explorer under "This PC" or the "Desktop"). Right-click on Simatic Shell and select Settings.
Ensure "Allow remote connection" is checked and the correct network card (IP address) is selected for communication. 4. Manual File Transfer (Workaround)
If the engineering station is failing to download the runtime project to the HMI or target PC, you can bypass the downloader entirely.
Compile the project on your engineering station to generate the .pdata or .fwc files.
Copy the project folder to a removable drive or network share.
Manually paste the files into the target path configured in the WinCC Runtime Loader on the destination machine. 5. Check SVG & Graphics Compatibility
In newer versions like WinCC Professional V18, certain graphical elements (like SVGs) might disappear in the Viewer RT if "Classic Mode" is active.
Disable Classic Mode in your runtime settings if SVG symbols are failing to display.
Ensure all screens are marked as Web-enabled in the WinCC Explorer properties before publishing. Still stuck? WinCCViewer RT - SiePortal - Siemens
If the viewer fails to connect or freezes, it is often due to a corrupted or incorrect configuration file (WinCCViewerRT.xml).
The Fix: Delete or rename the existing XML file to force a re-configuration. Standard File Locations:
Windows 7/10/Server 2008+: C:\Users\.
Older Systems: C:\Documents and Settings\.
Action: After deleting the file, restart WinCCViewerRT.exe. This will trigger the configuration dialog where you can re-enter the server IP and user credentials. 2. Run with Elevated Permissions
Some users report that the viewer only works when executed with administrative rights.
The Fix: Right-click on WinCCViewerRT.exe (found in ... \WebNavigator\Client\bin) and select Run as Administrator.
Persistence: To make this permanent, right-click the file > Properties > Compatibility tab > check Run this program as an administrator. 3. Repair the WebNavigator Client Installation
If the application refuses to start or files appear missing, the installation itself may be compromised. The Fix:
Open the Windows Control Panel and navigate to Programs and Features. Select the WinCC/WebNavigator Client. Choose Change/Uninstall and select the Repair option.
Restart the PC after the process completes to ensure all system files and group policies are applied. 4. Verify Network and Windows Features
For newer WinCC versions (like Unified), ensure your OS is prepared to handle the runtime environment.
Windows Features: Ensure ASP.NET 4.5 (or higher) and Internet Information Services (IIS) are enabled in "Turn Windows features on or off".
Firewall: Ensure the WebNavigator port (default 80 for HTTP or 443 for HTTPS) is not blocked by a local or corporate firewall. Quick Tips for Configuration WinCCViewer RT - SiePortal - Siemens
How to Resolve Common Issues with WinCC Viewer RT Downloads For automation engineers working with Siemens TIA Portal or WinCC, the WinCC Viewer RT (Runtime) is a critical tool. It allows you to monitor and control your HMI screens from a remote PC without needing the full WinCC engineering software installed.
However, users often run into roadblocks when trying to find a "WinCC Viewer RT download" or fixing connection errors. This guide covers how to properly acquire the software and fix common runtime issues. 1. Where to Download WinCC Viewer RT?
One of the biggest misconceptions is that WinCC Viewer RT is a standalone, third-party download. In reality, it is a component of the WinCC Runtime Professional or WinCC V7.x software packages. How to get it:
Check your Installation Media: If you have the original ISO or DVD for WinCC Professional or WinCC V7, the Viewer RT setup is located within the "Support" or "Additional Software" folders.
SIMATIC Net / WinCC Client: It is often installed automatically when you set up a WinCC Client or a WebNavigator Client.
Siemens Industry Online Support (SIOS): Siemens does not typically offer a "free" standalone download for Viewer RT. You must download the Service Packs (SP) or Updates for your specific WinCC version (e.g., V17, V18, or V19) from the SIOS portal. These updates often contain the latest fixes for the viewer. 2. WinCC Viewer RT "Fix": Common Troubleshooting
If you already have the viewer but it isn't working, here are the most effective fixes for the most common errors. Fix A: "Server Not Available" or Connection Failures
This is usually a network or credential issue rather than a software bug.
Ping the Server: Ensure your remote PC can see the Runtime server.
User Permissions: The Windows user on the remote PC must also exist on the WinCC Server with the exact same password, and must be part of the "SIMATIC HMI" user group.
Simatic Shell: Open "Simatic Shell" on both the server and the client. Ensure they are on the same terminal bus and can "see" each other in the shell window. Fix B: Configuration File (.pnc) Issues
WinCC Viewer RT relies on a .pnc configuration file to know which server to connect to.
The Fix: Run the WinCC Web Configurator on the server to ensure the web pages are published correctly. Then, recreate your .pnc file on the client PC by running the "WinCC Viewer RT" application and selecting "New" to input the server's IP and the start screen. Fix C: Update the WebNavigator Component
If the Viewer RT crashes or displays "White Screens," it’s often because the version of the viewer doesn't match the server's Service Pack.
The Fix: Go to the WinCC Server's web page via Internet Explorer/Edge (using the server's IP address). There is usually a link on the login page to "Download Client Components." Re-installing the WebNavigator client from the server itself ensures version compatibility. 3. Firewall and Port Settings
If your download and installation are perfect but the viewer still won't connect, your firewall is likely blocking the traffic.
Required Ports: Ensure Port 80 (HTTP) or Port 443 (HTTPS) is open.
Scripting: If you use complex C-Scripts or VB-Scripts, ensure that the "WinCC Runtime" is allowed through the Windows Defender Firewall on both ends. Summary Checklist
Don't look for a standalone download; use your WinCC installation media or SIOS updates.
Match versions: Ensure the Client Viewer version matches the Server's Service Pack.
Check Simatic Shell: Ensure the communication path is active. Permissions: Sync Windows credentials and HMI User Groups.
By following these steps, you can bypass the frustration of broken links and get your remote monitoring back online.
