## Problem

The error message “Unable to mount WIM file in the WinPE path” may appear in the following scenario:

- When creating USB, ISO, or PXE media using **WinPE Tool version 10**

## Cause

1. Windows firewall or Antivirus might block the WinPE (DISM) process.
2. Required privilege is not held by the user (Group Policy restriction).
3. Using a ReFS file system.

## Resolution

To identify if the Windows firewall is blocking the WinPE (DISM) process, follow the steps given below in the machine where the Central server (for on-premises) or Distribution Server (for cloud) is installed:

1. Exclude the Central Server (for on-premises) or Distribution Server (for cloud) installed location from firewall.

To ensure that the required privileges are held by the client, follow the steps given below:

1. Run **gpedit.msc** to open the group policy editor.
2. Navigate to **Computer Configuration > Windows Settings > Security Settings > Local Policies > User Rights Assignment > Manage auditing and security log.**
3. Ensure that the user account used to run the Central Server is added to this list.

To check the user account currently running the Central Server:

1. Run **services.msc** to open services and go to the properties of **ManageEngine Endpoint Central Server (for on-premises)** or **ManageEngine UEMS Distribution Server (for cloud)**.
2. Click the **Log On** tab.

3. Enter the username and password of the currently logged-in Windows user.
4. Click OK.
5. Restart the Central Server (for on-premises) or Distribution Server (for cloud).
6. Go to the **Deploy** tab and click **Create bootable media** to create bootable media.

To check the manual mount process, follow the steps given below in your **Central Server-installed machine** (for on-premises) / **Distribution Server-installed machine** (for cloud):

1. Search for Deployment and Imaging Tools in the Start menu.
2. Run Deployment and Imaging Tools as an administrator.

3. Run **copype amd64 "path\mount_check"** where **path** indicates the location to which the WinPE files should be copied.

   - For the on-premises solution, the path should be the server installed location.
   - For the cloud solution, the path should be **C:\Program Files (x86)\ZOHOCORP**

4. The **mount_check** folder will now be created on your computer.

5. Download this [bat file](https://www.manageengine.com/products/desktop-central/scripts/Mount_Check.bat) (SHA 256 Checksum: Loading...).

6. Navigate to mount_check -> media -> sources and copy the bat file to that folder.

7. Open Deployment and Imaging Tools environment in admin mode and then use the cd command to navigate to the path **"C:\Program Files (x86)\ZOHOCORP\mount_check\media\sources"** for cloud. For OP, navigate to the path **"<server_installed_path>\mount_check\media\sources"**

8. Next, run the bat file by typing `Mount_Check.bat` in console.
