Can not open Install.wim, error "Wrong format"

Recommended Posts


Iam trying to make a answer file for Win 10 unnatended install.

Downloaded the Win 10 ISO using Microsoft media creation tool.

Using Windows Sytem Image Manager Ver.10.0.10240.16384

When opning Install.wim I get this Error:


0.06 : This application requires version 10.0.10240.16384 of the Windows ADK.

Install this version to correct the problem

10.06 : Error opening Windows image at C:\Users\Administrator\Desktop\install.wim.

10.06 : System.ComponentModel.Win32Exception (0x80004005): Wrong format


   ved Microsoft.ComponentStudio.ComponentPlatformInterface.WimFileHandle..ctor(String wimPath)


   ved Microsoft.ComponentStudio.ComponentPlatformInterface.WimInfo..ctor(String wimPath)


   ved Microsoft.ComponentStudio.ComponentPlatformInterface.Cpi.OpenWim(String wimPath)


   ved Microsoft.ComponentStudio.ImagePicker.GetImageInfoFromPath(String path)


   ved Microsoft.ComponentStudio.ImagePicker.ValidateImageFileOrFolder(String fileOrFolder)


Iam using Ver.10.0.10240.16384 !  Does anyone know what is wrong?



Converted  Install.wim (ESD) to Install.wim using Nlite, problem solved.

The media creation tool ISOs are not the same as the MSDN ones. They did something to make them not open the same way. I am not sure what it is but there is something different. However there is a way around this. If you change your user agent of your browser to linux or mac then go to the media creation tool page it takes you to a different page for downloading the ISO and not the tool when you click to download the tool. These ISOs should work for what you need.

So in your original attempt, did you rename install.esd to install.wim?

 No I did not. Itried to open it as WIM ...but no Go. Used nlite to save it as WIM.(same file) Then I could open it using Windows Sytem Image Manager.
