Fix 0x8004100e BitLocker MBAM error on Windows

The 0x8004100e BitLocker MBAM error on Windows occurs when an MBAM agent tries to connect to the MBAM server and fails to send encryption details. The error may also occur when you try to run C:\Program Files\Microsoft\MDOP MBAM\MBAMClientUI.exe. This error may indicate or translate to WBEM_E_INVALID_NAMESPACE. In this post, we will look at the best ways to fix the 0x8004100e BitLocker MBAM error on Windows. Some users reported that the error occurs repeatedly after some minutes or seconds.

BitLocker Driver Encryption is a Windows encryption and system security feature that enables Windows PC users to encrypt any entities in the driver where Windows OS is installed. This protects the user’s data from unauthorized access or even theft. On the other hand, Microsoft BitLocker Administration and Monitoring (MBAM) offers an administrative interface that users can utilize to manage BitLocker Drive Encryption.

What are the causes of the 0x8004100e BitLocker MBAM error?

There are several reasons you can get BitLocker MBAM error code 0x8004100e, but the main one is the unregistered BitLocker WMI (win32_encryptablevolume) class or a missing registration. If the WMI class is not registered, it prevents your system from communicating well with the MBAM server. Unreadable registry keys may also trigger error code 0x8004100e. This happens when the Windows Registry is cluttered.

Another cause of Bitlocker MBAM error code 0x8004100e is improper program installation. This can leave incorrect entries for programs that do not exist on your PC, making your system function abnormally. Other possible causes of the 0x8004100e BitLocker MBAM error could be some background programs running on your computer, antivirus software, or incorrect configurations of certain programs.

Fix 0x8004100e BitLocker MBAM error on Windows

When you get 0x8004100e BitLocker MBAM error, it may mean that the WMI MSCluster Namespace is not there. Without the namespace, the system won’t connect to the MBAM server. To fix the 0x8004100e BitLocker MBAM error on Windows, run the following solutions:

1. Re-register the BitLocker WMI class
2. Disable background programs
3. Temporarily disable third-party antivirus software
4. Clean up Windows Registry files

Let us look at these solutions one by one in detail.

1] Re-register the BitLocker WMI class

If the BitLocker WMI class (win32_encryptablevolume) is not registered, it can cause the error code 0x8004100e when you try to perform a task on it. The solution for this is to re-register the WMI class, and this is how you do it:

• Type Command Prompt in the Windows search box and select Run as administrator.
• You will get a popup User Account Control message asking if you want to make changes; select Yes to continue.
• You may copy and paste or type the command line below and press Enter on your PC keyboard:

mofcomp.exe c:\windows\system32\wbem\win32_encryptablevolume.mof

This is the command to compile the MOF file, and once it’s successful, you may get a message like this:

Parsing MOF file: win32_encryptablevolume.mof
MOF file has been successfully parsed
Storing data in the repository…
Done!

This should solve the issue, and MBAM will be able to send encryption status data on the SQL server to the Compliance Database of MBAM.

2] Disable background programs

Turning off some background apps on your PC may also resolve the 0x8004100e BitLocker MBAM error. Some apps may interfere with the normal functions of a computer and result in temporary errors. Disabling them can block any issues that destabilize PC utilities like BitLocker.

3] Temporarily disable third-party antivirus software

Some antivirus software can cause an array of issues, like BitLocker MBAM error code 0x8004100e. Disable the third-party antivirus software and see if the error is fixed. These programs can alter some of the functions in your PC or even block some files or processes.

4] Clean up Windows Registry files

Microsoft does not support any registry cleaners, but we can use its Disk Cleanup utility. The tool can be used to clean up apps and drivers’ leftovers that may trigger the 0x8004100e error. Some registry files might be corrupted or cluttered, and the best way to fix this is by running the inbuilt Disk Cleanup tool. To run the Disk Cleanup utility, follow the steps below:

• Type Disk Cleanup in the Windows search box and click Open. Wait as the tool tries to calculate the size of files that can be deleted permanently.
• A new small window will pop up. You may select the files to delete by ticking the box next to them.
• Click OK and wait for the tool to clean up your disk.
• Once it’s done, reopen the Disk Cleanup tool and select Clean up system files
• Again, wait for the tool to calculate the amount of space that can be cleaned up.
• Another small window will pop up. Navigate through the Disk Cleanup and More options to locate extra files to clean up including leftovers by nonexisting programs.
• Once you are done with file selection, click OK and let the tool delete them automatically.

If you do not want to go through all those steps, you can use recommended free registry cleaners and junk file cleaners

We hope something here helps you fix the 0x8004100e BitLocker MBAM error on Windows.

How do I start MBAM encryption?

To start MBAM encryption, you may use the MBAM Client Control Panel, also known as BitLocker Encryption Options, which is available under System and Security. You will be able to start it when you have installed the MBAM Client. You can start the MBAM encryption by opening the Control Panel and then selecting System and Security. Double-click on the BitLocker Encryption Options. This will open a customized MBAM control panel. Here, you will view all available hard disk drives and their respective encryption status. You can also configure, update, and manage your passwords and PIN.

Where is the BitLocker recovery key in BIOS?

Before you enable BitLocker on your PC, the BIOS needs to be configured in order to support the service. To access the BitLocker configuration in BIOS, press either F10, Del, or F2 before Windows starts to load. The BIOS launcher key depends on the PC manufacturer. Once the BIOS is open, locate the TPM (Trusted Platform Module) Security and tick it to enable it. Once TPM is configured, you can now reboot your computer and enable BitLocker.
