.NET framework is crashing. I went to Event viewer. I click on .NET Runtime and tried to click on the link but the link does not work.

Sparrow.Utils.IncorrectDllException: librvnpal version might be invalid, missing or not usable on current platform. Initialization error could also be caused by missing 'Microsoft Visual C++ 2015 Redistributable Package' (or newer). It can be downloaded from https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads. Arch: Arm64, OSDesc: Microsoft Windows 10.0.26200

    Hi, I'm Bernard, a fellow Windows user. I'm happy to help!

    Kindly follow the steps provided by Q&A Assist. If the issue persists, kindly follow the steps below:

    Method 1. Download and Repair .NET Framework.

    Kindly download and repair the Framework using this link: https://www.microsoft.com/en-us/download/details.aspx?id=30135

    Once done downloading and running, try restarting the device and check.

    Method 2. Uninstall and reinstall .NET Framework

    Press the Windows key + R, then type in:

    optionalfeatures

    Then hit OK

    Uncheck for .NET Framework 3.5, then follow the prompt and restart the PC.

    Once the PC is booted again.

    Press the Windows key + R, then type in:

    optionalfeatures

    Then hit OK

    Click on Turn Windows Features on or off

    Check for .NET Framework 3.5, then follow the prompt and restart the PC.

    If none will work from the above solutions work, I suggest doing an in-place upgrade, wherein it will update the device to the latest version and repair all issues without deleting any files.

    It seems that you are experiencing a crash related to the .NET framework, specifically due to an issue with the librvnpal version. The error message indicates that this library might be invalid, missing, or not usable on your current platform (Arm64). Additionally, it suggests that the initialization error could be caused by a missing 'Microsoft Visual C++ 2015 Redistributable Package' or a newer version.

    To resolve this issue, you can take the following steps:

    1. Install the Microsoft Visual C++ Redistributable Package: Download and install the latest supported version from the Microsoft support page. This package is essential for running applications developed with Visual C++.
    2. Check for Updates: Ensure that your Windows operating system is up to date, as updates can sometimes resolve compatibility issues.
    3. Repair .NET Framework: If the issue persists, consider using the .NET Framework Repair Tool to repair your .NET installation.
    4. Reinstall .NET Framework: If repairing does not work, you may need to uninstall and then reinstall the .NET Framework version that your application requires.

    If these steps do not resolve the issue, you may need to consult the application publisher for further assistance.
