Hi @Ulf Tegnelov (DHL SE) ,

Thank you for the update, and I'm glad to hear the installation completed successfully.

Since this is a fairly common scenario, I'd like to summarize the issue and the resolution here so that other users who run into the same problem can refer to this thread for guidance.

Issue: The SSIS Projects extension for Visual Studio 2026 could not be installed in an offline environment, even after following the standard SSIS troubleshooting guide.

Resolution: Two changes resolved the problem:

Once local admin access was granted, the offline installation was able to run correctly.

In the Visual Studio Installer, the .NET Framework 4.7 targeting pack (Microsoft.Net.Component.4.7.TargetingPack) was not selected. After adding it, the offline package included all required prerequisites:

Microsoft.VisualStudio.Component.Roslyn.LanguageServices – C# and Visual Basic
Microsoft.VisualStudio.Component.CoreEditor – Visual Studio core editor
Microsoft.Net.Component.4.7.TargetingPack – .NET Framework 4.7 targeting pack

With these prerequisites in place, the offline installation completed as expected.

Thank you again for confirming the fix and sharing the details. Having it documented here will make it easier for others facing the same issue to find a solution. Please feel free to reach out if anything else comes up.

I hope my assistance and the information shared throughout this discussion have been helpful. If so, I would greatly appreciate it if you could follow the instructions here so that others with a similar question can benefit as well.

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.

Hi, not resolved yet. Your solution has been tested by our IT-department but they fails. So they are now trying to find out what's blocking the installation. Probably some security restriction in our managed environment.

Hi @Ulf Tegnelov (DHL SE) ,

Thank you for the update. I agree that the root cause is most likely the security restriction, especially since we've already performed a deep cleaning. If there was any version conflict, that step should have resolved it as well.

If your team discovers anything new, please feel free to share it in the comments, and I'll be glad to help. Otherwise, if you don't need any further assistance, kindly follow this guidance to close the ticket.

Hi @Ulf Tegnelov (DHL SE) ,

I just wanted to follow up and see whether your team was able to install SSIS successfully. Let me know if there are any updates or if there's anything else I can help with. Thanks!

Thx, will do so.
Current status is that IT-department is trying to solve the issue. They are investigating this: Believe the VSIXInstaller.exe is the machine level installer and prevent users from executing on system level settings..

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.

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:
  - Integration Services
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.
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.
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.
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.
