The error message you are encountering, stating that "9252.exe is not a valid Win32 application," typically indicates that the executable file you are trying to run is either corrupted, incompatible with your system architecture (e.g., trying to run a 64-bit application on a 32-bit system), or not intended for your version of Windows. Here are some steps you can take to resolve this issue:
- Check Compatibility: Ensure that the version of Windows 10 you are trying to install is compatible with your Sony Vaio laptop and that it meets the system requirements for Windows 10.
- Download the Correct Installer: Make sure you are using the official Windows 10 installation media. You can download the Media Creation Tool from the Microsoft website to create a bootable USB or download an ISO file.
- Run as Administrator: Right-click on the installer and select "Run as administrator" to ensure that you have the necessary permissions to execute the file.
- Check for Corruption: If you downloaded the installer, try downloading it again to ensure that it is not corrupted.
- Use a Different Installation Method: If the issue persists, consider using the Windows 10 Upgrade Assistant or creating a bootable USB drive to perform the upgrade.
If you continue to experience issues, you may want to check for specific error codes related to the upgrade process, as they can provide more insight into the problem.
