Error 0xc1510111: You do not have permission to mount and modify this image

Windows Permissions help determine which users can access, modify, and delete files and folders in your environment. Every file and folder on your Windows computer has individual permissions settings. Here are some guides relating to WDS. BOOTP Vendor Extensions and DHCP Options.

You may run into the following error below if you wish to mouth a boot.wim or install.wim file. In my case, it was the install.wim file. To resolve the issue, follow the instructions described below.

Error: 0xc1510111 You do not have permissions to mount and modify this image
Deployment Image Servicing and Management tool
Version: 10.0.10586.0
Error: 0xc1510111
You do not have permissions to mount and modify this image.
Verify that you have Read/Write permissions or mount the image using the /ReadOnly option. Note that you cannot commit changes to an image with read-only permissions

For a similar issue, see how to resolve “Error 740: Elevated permissions are required to run DISM“. Also see, You require permission from trustedinstaller: How to delete or rename files protected by Trusted Installer and Folder Access Denied, you require permission from SYSTEM: Unable to delete old windows folder.

To resolve this issue, follow the steps described below.

  • Log into Windows as an administrator or Domain Admin (or similar privilege)
  • Right-click on the install.wim file
  • Select Properties.
  • In the file property window, as shown below, on the General tab, uncheck the Read-only option. This was checked previously.

This will look like this below after it has been unchecked.

Now that you have decided to unset the read only file, you will be asked to apply changes to this folder, subfolders and files.
– Just click on OK and finally click on OK again.

Note: This steps depends on your security layout in your environment. You may also need to take ownsership and full control permission on your account.

To do this follow the steps described below.
– Click the “Security” tab.
This will display a list of groups and users that currently have permissions for the object.
– Click on Advanced settings
– Now you can take ownership of this file and add yourself (or a user to the permission entries with the adequate rights).
– Click on Apply and then ok.
– Close all windows and you should be able to out your image as shown below.

As you can see the mount process is about finishing. That is how to resolve the issue “do not have permissions to mount and modify this image”.
