    Hi @Deep Petale,  

    Welcome to Microsoft Q&A forum.

    Thank you for reaching out regarding the error message you are encountering. The error api-ms-win-shcore-scaling-l1-1-1.dll typically occurs on Windows 7 because this specific library is part of the Display Scaling API found in newer versions of Windows (8.1 and 10).

    To help resolve this issue, please follow these troubleshooting steps:

    1/ Install the Universal C Runtime

    • This update is essential for Windows 7 to process modern DLL calls.
    • Visit the Microsoft Update Catalog.
    • Download and install the version appropriate for your system architecture (x64 for 64-bit or x86 for 32-bit).
    • Restart your computer after the installation is complete.

    2/ Update Microsoft Visual C++ Redistributable

    This file is often included in the latest Visual C++ packages.

    • Download the Visual Studio 2015, 2017, 2019, and 2022 redistributables from the official Microsoft support page.
    • I recommend installing both the x86 and x64 versions to ensure full compatibility.

    3/ Run System File Checker (SFC)

    If the above updates do not resolve the issue, please check for corrupted system files:

    • Open the Start menu, type cmd, right-click it, and select Run as Administrator.
    • Type sfc /scannow and press Enter.
    • Once the scan reaches 100%, restart your PC.

    Because Windows 7 is no longer officially supported by Microsoft, some newer software may require features only available in Windows 10 or 11. If the error persists after these steps, please check if the software provider offers a "Legacy" or "Windows 7 compatible" version of the application.

    Please let me know if you have any further questions or if the issue persists.
