The DCOM 10016 error is caused by a program that tries to start the DCOM server and uses the DCOM infrastructure, but the user does not have the necessary permissions to do so.
The error is synonymous with Windows Server, but it can also occur on Windows 7, 8, or 10. The error occurs because your system cannot interact with a particular “DCOM” (Distributed COM) process. These are the new edition of Microsoft’s infamous “COM” objects – an EXE or DLL that allows your system to load a number of intercom technologies. In summary, COM objects are used by many fundamental applications / processes to enable a number of extensive functions.
The error message will normally appear as follows:
The application specific permission setting does not grant local activation permission for the COM server application with CLSID {9E175B6D-F52A-11D8-B9A5-505054503030} and APPID {9E175B9C-F52A-11D8-B9A5-505054503030} to the user PCNAME Username SID S- 1-5-21-81864976-3388411891-1937036257-1001 from LocalHost address (using LRPC) running in application container SID not available (S-1-15-2-1430448594-2639229838-973813799-439329657 -1197984847-4069167804-1277922394). This security permission can be modified through the Component Services administrative tool.
This particular error is displayed when you are trying to load an application that requires administrator access to one of its dependent libraries. If there is no administrator access, the above error will appear.
The solution is to add the correct user to the “Administrators Group” in Windows …
1. Reg Edit
The first step is to edit the settings within the registry that will cause the error to be displayed.
To do this, follow these steps:
-
Press the “Windows” + “R” keys on your keyboard
-
In the “Run” dialog box, type “regedit” and hit “OK”
-
Look for the following:
– HKEY_Classes_Root
– CLSID
– [[ CLSID cited in the error ]]
-
Right click and select “Permissions.”
-
Click “Advanced” and change the owner to the “Administrators” group.
-
Also click on the box that will appear below the owner’s line. (“Replace owner …”)
-
Click “Apply”
Next (still in Reg Edit), do the following:
-
Look for the following:
– HKEY_LocalMachine
– Software
– Lessons
– AppID
– [[ AppID cited in the error ]]
-
Right click and select “Permission”
-
Click “Advanced” and change the owner to the “Administrators” group.
-
Check the box “Replace owner …”
-
Click “Apply”
Finally (exit Reg Edit), you need to load “Administrative Tools” and edit various options:
-
Press the “Windows” + “R” keys on the keyboard
-
In the “Run” dialog box, type “control panel” and click “OK.”
-
From “Control Panel” select “Administrative Tools”
-
Select “Component Services”
-
Under “Computers”, click “Computer” and then “DCOM Settings”
-
Look for the service mentioned by the error
-
Right click and select “Properties”
-
Click on the “Security” tab and select “Add User”
-
Add “Local Service” and then click “Apply”
-
Check the box “Activate local”
After doing this, try running your application again. It should work. Otherwise, you will need to right-click and select “Run as administrator” on its icon.
While this error is somewhat obscure, there is plenty of help available on the internet if you still need it.
For more help, you may want to consult someone with more specific knowledge of your system, primarily for a second opinion.
You can do this by taking your computer to a local repair technician, or (if you don’t want the hassle / expense) use one of the online communities. If you want to use one of the online communities, your first port of call should be the “Questions / Answers” websites that are there to help you get specific feedback on issues by asking “questions” of your large communities. The best of these sites are Microsoft Answers and SuperUser.
If you want to use them, please register and post the error message you receive in a new question. Be sure to also include the context in which the error is displayed (when it is displayed, any additional issues, etc.).
You will probably receive responses in a couple of hours (2/3 hours) and their quality will depend on the respondent. For most questions, the answers tend to be final (from Microsoft Answers) or a bit more researched (SuperUser).
You wouldn’t trust any of these comments, but would use them to form an opinion on what might be specifically wrong with your system. This particular bug is pretty obscure and therefore will generally require some kind of specific fix to get it working again.
