Setup: Cannot Locate Toolkit Documentationx86enusmsi New

How to Fix the Error: "Setup cannot locate toolkit documentation-x86_en-us.msi"

The error "Setup cannot locate toolkit documentation-x86_en-us.msi" is a common roadblock when installing the Windows Assessment and Deployment Kit (ADK) or integrating it with tools like Microsoft Configuration Manager (SCCM). This typically occurs when the installer cannot reach Microsoft’s servers to download a specific component or when the local installation media is incomplete. Why This Error Happens

This error is usually triggered by one of the following scenarios:

Offline Installations: Trying to run the ADK setup on a machine without an active internet connection.

Network Restrictions: A firewall, proxy, or ISP blocking the download of .cab or .msi files.

Antivirus Interference: Security software incorrectly flagging the download as a threat and blocking the file.

Corrupt Installation Media: The setup files were partially downloaded or corrupted during the initial process. Step-by-Step Solutions 1. Download the Full Offline Installer setup cannot locate toolkit documentationx86enusmsi new

Instead of running the small "web" setup file, you should download the entire ADK toolkit on a computer with a stable internet connection and then transfer it to your target machine. Run the ADK setup file (adksetup.exe).

When prompted for the installation path, select "Download the Assessment and Deployment Kit for installation on a separate computer".

This will download all required .msi and .cab files, including the missing toolkit documentation, to a folder you specify.

Copy this entire folder to your offline machine and run adksetup.exe from there. 2. Check Antivirus and Firewall Settings

Third-party antivirus programs often block background downloads required by Microsoft installers. Temporarily disable your antivirus software.

If you are on a corporate network, ensure that .cab and .msi file downloads are not blocked by the web filter or firewall. 3. Clear the Installer Cache and Temporary Files How to Fix the Error: "Setup cannot locate

Sometimes residual files from a failed previous attempt prevent the new installation from finding its path. Navigate to your %TEMP% folder and delete its contents.

Run the Windows Installer Service manually to ensure it is active. You can find this by typing services.msc in the Start menu, right-clicking Windows Installer, and selecting Start. 4. Use PowerShell to Fetch Missing Files

For advanced users, you can use a PowerShell script to specifically target and download missing ADK files from Microsoft's redirect URLs. This ensures you are pulling the exact version (like ADK 1903 or 2004) required by your system. Installing Windows ADK error - Spiceworks Community

4. Quick Workaround (If Docs Not Required)

If the MSI allows ignoring missing documentation: (Requires the MSI to support feature selection)

msiexec /i installer.msi ADDLOCAL=ALL REMOVE=Documentation /qb

Why Does the Installer Need Documentation Files?

Older Microsoft setups often included local help documentation (.chm, .hxs, or .mshc files). The installer checks for these files to:

  1. Register them with the local Help Library Manager.
  2. Ensure integrity of the full product installation.
  3. Create shortcuts or menu entries for documentation.

If the setup routine cannot find the expected documentation toolkit, it aborts or throws a fatal error.

Resolution steps

  1. Re-download or re-copy the full installer package from the original source to ensure completeness.
  2. If the MSI is present but named differently, rename it to match the installer’s expected name (use the original filename shown in the installer log or UI).
  3. Repair the installation source:
    • If using an ISO, mount it and run setup from the mounted image rather than from inside an extracted folder.
    • If using a web installer, download the full offline installer if available.
  4. Clear Windows Installer temporary cache:
    • Stop the installer, delete temporary extraction folders (e.g., %TEMP%), then re-run setup as Administrator.
  5. Check permissions on the installer folder and ensure SYSTEM and Administrators have read/execute rights.
  6. Review installer logs for the exact file path the setup tried to access (look for "Cannot find" or MSI filename) and place the MSI at that path or update the installer source accordingly.
  7. If an earlier partial install exists, uninstall related components, reboot, then attempt fresh install.
  8. Contact the software vendor to obtain the missing Toolkit Documentation MSI or an updated installer if the package is known to be broken.

Fix 2: Extract All Files from ISO or Archive Before Installing

Many users double-click an ISO file or open a ZIP and run setup directly from the virtual drive. This can cause path resolution errors.

Correct method:

  1. Right-click the ISO file → Mount (or use 7-Zip/WinRAR).
  2. Copy the entire contents to a local folder, e.g., C:\Temp\SDK_Setup\.
  3. Run setup from that local folder as administrator.
