Solution # 3 Checking the system for viruses and malware

Next, you need to wait for the Windows scan to complete, and then remove all found threats from your system. Once you’re done with your antivirus, check for an error with the D3DCompiler_47.dll file.
Solution # 4 SFC scan
You may have encountered problems launching a required application due to corrupted system files. In such a situation, the SFC system utility will help you, which is able to find damaged files and restore them, if possible. To get the SFC to work, you need to do the following:
- right-click on Start;
