Your installer source files are not corrupted or blocked by network policies.
If listed, select it and let the tool repair the corrupted registry endpoints. 5. Disable Conflicting Security Software
This issue typically arises in one of three scenarios:
Check if toolkit_documentation_x86_enu.msi (or a similarly named file) is present. If found, run that specific .msi file first, then restart the main setup. 3. Change Windows Installer Logging and Paths setup cannot locate toolkit documentationx86enusmsi new
This error usually happens when a software installer (likely for a Microsoft SDK or older developer toolkit) can't find a specific help file it needs to finish. Why this is happening
Microsoft provides a free, automated tool to fix issues when programs cannot be installed or removed.
The error message is a common obstacle encountered by systems administrators and IT professionals when installing or updating the Windows Assessment and Deployment Kit (ADK) . This specific installation failure completely stalls deployment preparation pipelines, blocking critical components like the Windows Preinstallation Environment (WinPE) and Windows System Image Manager (WSIM). Your installer source files are not corrupted or
Or the error might be a concatenation of a variable: setup cannot locate "toolkit documentation\x86\en-us\msi new"
Proceed through the setup wizard to see if the error is bypassed. 2. Extract the Installer Manually
Encountering an installation error just as you are about to deploy a critical software development kit (SDK) or legacy Microsoft toolset is frustrating. One of the more obscure but increasingly common errors seen when installing older Microsoft tools (such as the Windows Driver Kit (WDK), the .NET Framework SDK, or certain Visual Studio legacy components) is: Change Windows Installer Logging and Paths This error
If you are a developer and this error appears when trying to or package your own toolkit:
Sometimes the file exists, but the installer looks in the wrong directory.
The error message typically appears during the setup of the Windows Assessment and Deployment Kit (ADK) or Windows Software Development Kit (SDK). While the message suggests the installer cannot find a specific MSI file, the real issue is often something else entirely.
| Workaround | How to do it | |------------|---------------| | | Create empty folders matching the expected path so the installer finds something . | | Extract MSI from setup | Use setup.exe /a (admin install) or setup.exe /x to extract contents without running full setup. | | Run in compatibility mode | Right-click setup.exe → Properties → Compatibility → Windows 7 or XP SP3. | | Re-download from official source | The copy you have may be truncated or repacked incorrectly. |
