Access is denied when querying restricted APIs or hardware logs.
Before diving into complex fixes, restart your PC. Sometimes the error occurs because a temporary process is stuck. A fresh boot can clear transient states. If the error reappears after reboot, move to Method 2.
Many Python libraries rely on C++ dependencies to run properly on Windows. If your computer is missing these core packages, the application will fail instantly. Go to the official Microsoft support website. failed to execute script mspm-source
Use or Dependencies (open-source) to see if any required DLLs (like VCRUNTIME140.dll , MSVCP140.dll ) are missing. Install the Microsoft Visual C++ Redistributable if needed.
| Cause | Explanation | |-------|-------------| | | Required packages not included during build | | File path issues | Script assumes relative paths for data files, but executable runs from different working directory | | Hidden imports | PyInstaller did not detect dynamically imported modules | | Missing DLLs / system libraries | e.g., libpython.dll , vcruntime140.dll | | Environment mismatch | Script tries to access environment vars that don’t exist at runtime | | Permissions | Executable cannot write to temp or log directory | Access is denied when querying restricted APIs or
Common missing modules include pandas , numpy , cryptography , or requests . Alternatively, use --collect-all for packages with data files:
The error typically occurs when a standalone executable (often built with PyInstaller ) fails to launch because it cannot find its entry point or a required dependency . This error is common in specialized software tools, such as those used for microcontroller development (e.g., TI's MSPM0 tools) or custom data management scripts. 1. Executive Summary A fresh boot can clear transient states
This error is most often caused by a corrupted download or an incomplete extraction of files. The executable cannot find the "source" script it needs to run.
