    Hi @Ulf Tegnelov (DHL SE) ,

    Thank you for following up and for sharing the details with me.

    After reviewing your log, it looks like there is a version conflict and leftover corrupted files. This usually happens when the SSIS extension was previously installed but not fully or cleanly removed, which can block a new installation.

    To resolve this issue, please perform a complete removal of Visual Studio to ensure a clean environment before reinstalling.

    Step 1: Uninstall Visual Studio Go to Settings > Apps > Installed Apps, and uninstall all Visual Studio versions, including the Visual Studio Installer.

    Step 2: Manually remove leftover files After uninstalling, open File Explorer and delete the following folders:

    C:\Program Files (x86)\Microsoft Visual Studio
C:\Program Files\Microsoft Visual Studio
%programdata%\Microsoft\visualstudio
%Temp%

    For the %Temp% folder, press Ctrl + A to select everything and delete it. If any files cannot be removed, simply choose Skip to continue.

    Step 3: Clean up registry entries Before proceeding, please back up your registry.

    Press Win + R, type regedit, then locate and delete the following keys (if they exist):

    HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\VisualStudio
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio
HKEY_CURRENT_USER\Software\Microsoft\Visual Studio

    These steps will completely remove all remaining components of Visual Studio, ensuring there are no leftover files or corrupted data. This provides a fresh and clean environment for a new installation.

    Since these steps involve system-level changes, please consult your IT department if needed.

    I look forward to your update.

    For SSIS Projects extension installation issues in Visual Studio 2026, use the same troubleshooting steps as for Visual Studio 2022, because the SSIS extension is shared between VS 2022 and 2026.

    1. Verify the SSIS extension is installed and enabled
      • In Visual Studio 2026, go to Extensions > Manage Extensions > Installed.
      • Confirm that SQL Server Integration Services Projects (SSIS extension) is listed.
      • If it is present but disabled, enable it and then restart Visual Studio.
      • If it is missing, install it from the Marketplace entry that is shared for VS 2022 and 2026:
    2. Check for known SSIS extension issues in VS 2022/2026
      The SSIS Projects extension for VS 2022+ has known issues documented in the troubleshooting guide, including:
      • Context menu entries appearing multiple times.
      • SSIS extension being uninstalled after a Visual Studio repair or update (requiring reinstallation).
      • Solution Explorer showing incompatible or The application is not installed even though SSIS is installed.
      For the incompatible / application is not installed case:
      • Open Visual Studio.
      • Go to Extensions > Manage Extensions > Installed.
      • Enable the SSIS extension.
      • Relaunch Visual Studio.
    3. Inspect the SSIS extension installation log
      If installation fails or behaves unexpectedly:
      • Open %temp%\SsdtisSetup.
      • Locate Microsoft.DataTools.IntegrationServices_{Timestamp}_ISVsix.log.
      • Review the log for error messages.
      If the log contains:
      • Pre-check verification failed with warning(s): AnotherInstallationRunning
        → Windows Installer is busy with another installation (Windows Update, MSI, etc.). Wait until other installations complete, then retry SSIS extension installation.
      If other errors appear in the log:
      • Download and run the PowerShell helper script VSInstallationTroubleShooting.ps1 from:
        https://github.com/Azure/Azure-DataFactory/blob/main/SamplesV2/SQLServerIntegrationServices/VSInstallationTroubleShooting.ps1
        This script is designed to help diagnose Visual Studio/SSIS extension installation issues.
    4. General Visual Studio installation troubleshooting
      If Visual Studio itself shows installation or upgrade problems that affect the SSIS extension:
      • Follow the guidance in Troubleshoot Visual Studio installation and upgrade issues to:
        • Check Visual Studio known issues for VS 2026.
        • Repair Visual Studio via the Visual Studio Installer.
        • If update failures occur, delete the Visual Studio Installer folder (C:\Program Files (x86)\Microsoft Visual Studio\Installer) and rerun the installer bootstrapper.
    5. If problems persist
      • Use the Report a Problem tool from Visual Studio or the Visual Studio Installer to submit the issue, including the SSIS installation log from %temp%\SsdtisSetup.
      • Optionally, use the Visual Studio installation chat support option for real-time help with installation-related issues.
