    Hi Rajarshi Sarkar It seems like the installation is failing during component staging, which could be due to permission issues, missing dependencies, or cached installation files.

    Here are some steps to troubleshoot:

    Check Event Logs: Look at the Windows Event Viewer for any relevant errors during the install. This can give more context about what’s failing.

    Inspect Dependencies:

    • WebView2: Kusto Explorer depends on WebView2. If it's missing, you can reinstall it from Microsoft's site.
    • MSAL: Issues with msalruntime.dll suggest a problem with Microsoft Authentication libraries. Make sure these are up-to-date.

    Clear Old Installations: Run this in PowerShell to clean up old files:

    
DISM /Online /Cleanup-Image /RestoreHealth

    Also, check for any MSI cache issues in C:\Windows\Installer (back it up before deleting).

    Re-run as Admin: Ensure you're running the installer as an Administrator and, if needed, in Compatibility Mode for an older Windows version.

    Try the Portable Version: If nothing else works, check if a portable version of Kusto Explorer is available and use that as a workaround.
