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 The "WinCC Viewer RT" download and installation issues
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
