If you are experiencing the DistributedCOM Error 10016 in your Windows 10, don’t fret because it is a common issue that can be fixed easily. This error occurs when the system is unable to access specific registry keys or when there is an incorrect configuration with the security permissions of the DCOM components. Here is a step-by-step guide on how to fix the DistributedCOM Error 10016 in Windows 10:

1. Open the Event Viewer

The Event Viewer is a tool in Windows that allows you to view details about system events and errors. To launch Event Viewer, press the Windows key + X and select “Event Viewer” from the list.

2. Locate the DistributedCOM Error

In the Event Viewer window, go to “Windows Logs” and select “System.” Look for the DistributedCOM Error 10016 in the list of events. Note down the details of the error, including the “CLSID” and “APPID” values.

3. Grant Permissions to the Registry Key

To fix the error, you need to grant permission to the registry key. Open the Registry Editor by pressing the Windows key + R, type “regedit” in the Run box, and hit Enter.

Go to the following location in the Registry Editor:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Ole

Right-click on the “Ole” key, select “Permissions,” and click on “Add.”

In the “Enter the object names to select” field, type “ALL APPLICATION PACKAGES” and click on “Check Names.”

Click on “OK” to add the group.

Select the “ALL APPLICATION PACKAGES” group and grant it “Full Control” permissions.

4. Grant Permissions to the DCOM Component

In the Registry Editor, go to the following location:

HKEY_CLASSES_ROOT\AppID\{AppID}

Replace “{AppID}” with the value of the “APPID” field from the Event Viewer.

Right-click on the AppID key, select “Permissions,” and click on “Add.”

In the “Enter the object names to select” field, type “ALL APPLICATION PACKAGES” and click on “Check Names.”

Click on “OK” to add the group.

Select the “ALL APPLICATION PACKAGES” group and grant it “Full Control” permissions.

5. Restart the Computer

Once you have granted permissions to the registry key and DCOM component, restart your computer to apply the changes.

6. Check for the Error

After the restart, open the Event Viewer and check if the DistributedCOM Error 10016 still occurs. If the error still persists, repeat the steps and make sure you have correctly granted permissions to the registry key and DCOM component.
