If you're seeing the error "d3dcompiler_47.dll was not found" when launching Microsoft Edge, it usually means a required system file is missing or not properly installed. The good news is that this issue can often be resolved without too much hassle. Here's how to fix it.

1. Reinstall or Repair Microsoft Edge
Sometimes, the problem stems from a corrupted or incomplete installation of Edge itself. A quick repair or reinstall can often bring back the missing DLL file.
- Go to Settings > Apps > Apps & features
- Search for Microsoft Edge , click on it, and select Modify
- Choose the Repair option if available
- If that doesn't work, uninstall Edge, then reinstall it from the official Microsoft website
This process ensures all necessary files—including d3dcompiler_47.dll
—are restored.

2. Install or Update DirectX Runtime
The d3dcompiler_47.dll
file is part of DirectX, a collection of tools that help games and apps run smoothly on Windows. If your DirectX components are outdated or partially missing, Edge might fail to start.
- Download the DirectX End-User Runtime Web Installer from Microsoft
- Run the installer—it will check your system and install any missing components
- Restart your computer after installation completes
This step makes sure that all essential DirectX files, including the d3dcompiler version 47, are in place.

3. Run the System File Checker (SFC)
Windows has a built-in tool called SFC that scans for and repairs missing or corrupted system files.
- Open Command Prompt as Administrator
- Type
sfc /scannow
and press Enter - Wait for the scan to finish—this can take several minutes
- If issues are found, the tool will attempt to fix them automatically
After running SFC, try opening Edge again to see if the error persists.
4. Check for Windows Updates
Missing DLL errors can also occur if your system is out of date. Microsoft regularly releases updates that include important system files and bug fixes.
- Go to Settings > Update & Security > Windows Update
- Click Check for updates
- Install any pending updates and restart your PC
Keeping your OS up to date helps prevent compatibility issues like this one.
If none of those steps work, consider doing a clean boot to rule out background programs interfering with Edge startup. But in most cases, one of the above methods should resolve the "d3dcompiler_47.dll was not found" error.
Basically that's it.
