RuntimeBroker - Launch and Activation Permissions - ADD is greyed out

I've been getting a few annoying DistributedCOM warnings (Event ID 10016) in Event Viewer such as...

The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID {2593F8B9-4EAF-457C-B68A-50F6B8EA6B54} and APPID {15C20B67-12E7-4BB6-92BB-7AFF07997402} to the user DESKTOP-AI976VT\keith SID (S-1-5-21-902422483-3872304736-3775899550-1001) from address LocalHost (Using LRPC) running in the application container Unavailable SID (Unavailable). This security permission can be modified using the Component Services administrative tool.

...and they often coincide with the Win10 OS crashing. I'm not sure the crash is related but there are no other Administrative Events in Event Viewer apart from these warnings so I tried to get rid of them. I edited the keys in the registry giving Administrators group and my personal windows user name Full Control permissions. Then I tried to access RunTime Broker following the procedure below.

Launch DCOMCNFG from command prompt running as Administrator.
Console Root > Component Services > Computers > My Computer > DCOM Config > Runtime Broker > Properties > Security > Launch and Activation Permissions > Edit
I get a popup "One or more of the permission entries attached to Registry Value has an unrecognized type and can not be displayed."



I clicked on OK
==> "Add..." is greyed out



So I'm stuck, cannot add Administrators group or my personal windows user name to the list.

Does anyone have a solution?

Do A search for error 10016 in the forum search box. There are plenty of answers to your problem. Hope that helped.

Couldn't find any help for when the ADD button is greyed out, only found answers to when the EDIT button is greyed out, which is not what's happening here.

Please don't waste your time trying to fix these common 10016 harmless 'errors'. You are likely to do more harm than good. All 6 PCs I look after have these errors.

Bit late to the party perhaps but to fix (Which is fine, DCOM can cause problems)

Step 1. Backup server fully.

Remaining steps
Go to Regedit HKEY_CLASSES_ROOT\AppID\
Right click the APPID-GUID key and back it up.
When done right click again, select permissions, advanced, and set ownership to administrators (Note to change location to local system, not domain).
When done assign administrators full permissions.
Reboot OS (Can try restarting service impacted instead)
Go to DCOM and set permissions.

Usually works. If not you could locate a same OS system which does not have the issue and compare permissions on the key. Set it the same. If still not either leave it alone unless you are experiencing issues, or give MS a buzz provided you have a support agreement with them or alternatively are ok to pay.
