A: No. Removing the startup reference or the script itself will not harm your operating system. At most, a specific McAfee scanning feature will stop launching automatically.
When a PyInstaller-packaged application crashes before it can fully launch or initialize its own error logging, Windows displays this standard pop-up. To fix it, you need to uncover the hidden Python traceback causing the crash. Step 1: Discover the Real Error via Command Prompt
Sometimes the script error is a symptom of deeper system corruption. Run System File Checker.
When a bundled application or system routine attempts to deploy an MSP (Microsoft Installer Patch) update, fetch tracking data, or source specific automation blocks, it invokes secondary background utilities. The error materializes under three core technical scenarios:
The most direct fix is to remove the shortcut or script from your startup routine. failed to execute script mspm-source
If your Command Prompt test revealed a ModuleNotFoundError , it means the script was compiled without all its necessary code libraries. If you are the of the software:
The phrase "failed to execute script" indicates that a Python script (wrapped into an executable) or a similar automated script was triggered to run—usually at startup—but Windows could not find the necessary file, path, or dependencies to run it.
The error can be attributed to one or more of the following:
Start by checking your Startup folders and Task Manager. In 90% of cases, deleting the entry from shell:startup or disabling it in Task Manager resolves the issue immediately. For persistent cases, Autoruns and the McAfee removal tool will finish the job. Run System File Checker
Clear your build cache before compiling again by running: pyinstaller --clean mspm-source.spec Use code with caution.
Ensure is installed (specifically x86 and x64 versions) [1].
If the executable was built on another machine, it might not be compatible with your environment. Re-download the application.
: Many Python-based executables require specific runtime libraries. Download and install the latest supported versions from the Microsoft Support Page Run as Administrator : Right-click the application icon and select Run as administrator type mspm-source .
If you cannot find the script in the folders, it may be hiding in the Windows Registry. Disable it via Task Manager.
: Right-click the .exe and select Run as Administrator to bypass potential permission restrictions.
This is the most effective way to stop the error by deleting the link that tells Windows to run the missing script. Download the official Microsoft Autoruns tool. Extract the ZIP and run Autoruns64.exe as . Wait for the "Ready" status at the bottom. In the Filter/Search box at the top, type mspm-source .
