    I had to copy the installer from the c:/ program files / Microsoft visual studio/ installer to the company PC, and then it worked. The vs 2026 didn't create the installer on closed network

      Hi

      when Visual Studio is installed on a machine with internet access, the setup process places the Visual Studio Installer application under C:\Program Files (x86)\Microsoft Visual Studio\Installer. On a closed network, the bootstrapper (vs_enterprise.exe) alone does not generate that installer component, which is why the installation window disappeared.

      By copying the installer folder from a machine where Visual Studio was already installed, you provided the missing component, which allowed the setup to continue successfully.

      For future offline installations, the recommended approach is:

      Create a full offline layout on a machine with internet access using the --layout command.

      Copy both the layout folder and the installer folder (C:\Program Files (x86)\Microsoft Visual Studio\Installer) to the offline machine.

      Run the installer from within the layout using --noWeb.

      This ensures the installer has everything it needs without trying to reach the internet, and avoids the issue you ran into on the domain network.

    Hello thanks for reaching out !
    Visual Studio offline installation step-by-step procedure

    1. Get installer online: On a PC with internet, download the latest Visual Studio 2026 vs_enterprise.exe.
    2. Create full layout: Open an elevated Command Prompt and run: vs_enterprise.exe --layout C:\LocalVSlayout --lang en-US --includeRecommended

    Verify files: Confirm the layout is complete:
    vs_enterprise.exe --verify C:\LocalVSlayout

    Transfer safely: Copy the entire C:\LocalVSlayout folder to a USB drive, then to the offline work PC (e.g., C:\LocalVSlayout).

    • Run locally as admin: On the work PC, open an elevated Command Prompt and run:

    C:\LocalVSlayout\vs_enterprise.exe --noWeb --noUpdateInstaller

    • Avoid network interference: If the installer shows “Verifying” then closes, disable the network adapter temporarily and rerun the command.
    • Disable proxy/CRL checks (temporarily): Turn off Windows proxy settings and uncheck “Check for publisher’s certificate revocation” in Internet Options → Advanced; retry, then restore settings after install.
    • Check policies: Ensure AppLocker/WDAC/EDR aren’t blocking vs_enterprise.exe or vs_installer.exe; if needed, ask IT to whitelist them.
    • Review logs if failure persists: Check %TEMP%\dd_bootstrapper*.log and %ProgramData%\Microsoft\VisualStudio\Setup\ logs for specific errors.

      Visual Studio 2026 introduced stricter installer verification and network policy checks, so it fails in offline corporate networks. VS 2022 works, but it doesn’t support .NET 9 with Docker offline, which requires VS 2026.

      Just want to add that we are also seeing the same thing. I have disabled revocation checks and installed the 3 certificates in the layout's certificates folder per the documentation. dd_bootstrapper log file shows "Error 0x80131509: Signature verification failed. Error: Unable to verify the integrity of the installation files: the certificate could not be verified."

      I am not sure if the above comment @Anonymous is supposed to indicate something changed but I just re-downloaded the layout and got the same error message so either nothing changed or it's not resolved yet.

    It does working with vs 2022 so why it doesnt work with vs 2026, what changed?

    but the vs 2022 doesnt support .net 9 with docker offline.

      same experience here. I tried to download the whole installer but apparently it's not downloading the workload for .net web and .net desktop management. from how it behaves, seems like the installer will crash in run with the --noWeb switch if the workload is not downloaded.

    It sounds like you're experiencing issues with the Visual Studio installer when trying to run it in a network environment without internet access. Here are a few things to check:

    1. Certificates: Ensure that the necessary certificates are installed on the client machine. If the installer is trying to verify the installation and fails, it might be due to missing certificates. You can find guidance on installing updated certificates for offline installations in the documentation.
    2. Network Permissions: Make sure that the user or system account running the installation has proper access to the network share that contains the layout. Insufficient permissions can cause the installer to fail.
    3. Using the --noWeb Switch: When using the --noWeb switch, ensure that all required components are included in the local layout. If any components are missing, the installation will fail. The installer will not be able to download any missing components from the internet.
    4. Layout Path: Verify that the path to the local layout is correct and accessible from the machine you are trying to install on.

    If these steps do not resolve the issue, you may want to consult the troubleshooting documentation for network-related errors or consider reaching out to support for further assistance.
