how to fix dcom error

You might have encountered the notorious distributedcom 10016 error or DCOM event ID 10016 on your Windows 10 OS. It is a known error and it has been around since the Windows 8 era.

Unfortunately, the error does not seem to resolve even after an upgrade. It arises due to the lack of user permissions when an application tries to start the DCOM server. 

Although the error is not known to cause any serious damages to your operating system, it might be annoying to deal with it all the time. It is delivered to the user in the form of a system error, along with a message having an APPID and CLSID. It is just because both of them are unique for every app and they are required to allow application-specific permissions.

Please have a look at these 2 solutions that can help you remove the Windows 10 distributedcom 10016.

  20. Click Edit against the Launch and Activation Permissions. (Click Remove if you receive the following warning one or more permissions entries attached has an unrecognized type)
  21. Now find System under the list of users. Click the Add button if you are not able to locate it, type System and hit the OK button.
  22. You will now be able to select System under the user’s list in the current window. Look for Local Launch and Local Activation and select Allow.

Finally, you will find some other ClSID and AppID values. Repeat the following steps for all of those values that have been listed in the event logs.  The changes will take effect after you restart your system at the end.

Although the second solution seems to be a long and hectic one, it is only recommended for those users who are not able to resolve the error through the first method.
