Event ID 10016 - The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID

What?

"It can't be set it's dimmed" according to Bing translator.

Same thing here. Greyed out. Windows 8.1 seems to fill the Event viewer with far more errors than previous versions.

edit: OK, found out why it was greyed out. There are 2 reg keys you have to set permissions to before you go to the DCOM Configuration in Component services. The CLSID key and the APPID key.

From another forum, although it applies to a different app, same principle:

*1. Open Regedit.2. Go to HKEY_Classes_Root\CLSID\*CLSID*.Note: *CLSID* stand for the ID that appears in your event viewer error. In your case, it's {C2F03A33-21F5-47FA-B4BB-156362A2F239}.3. Right click on it then select permission.4. Click Advance and change the owner to administrators. Also click the box that will appear below the owner line.5. Apply full control.6. Close the tab then go to HKEY_LocalMachine\Software\Classes\AppID\*APPID*.Note: *AppID* is the ID that appears in your event viewer. In your case it's {316CDED5-E4AE-4B15-9113-7055D84DCC97}.7. Right click on it then select permission.8. Click Advance and change the owner to administrators.9. Click the box that will appear below the owner line.10. Click Apply and grant full control to Administrators.11. Close all tabs and go to Administrative tool.12. Open component services.13. Click Computer, click my computer, then click DCOM.14. Look for the corresponding service that appears on the error viewer.15. Right click on it then click properties.16. Click security tab then click Add User. Add SYSTEM then apply.17. Tick the Activate local box.So use the relevant keys here and the DCOM Config should give you access to the greyed out areas:*CLSID:

{D63B10C5-BB46-4990-A94F-E40B9D520160}

and APPID

{9CA88EE3-ACB7-47C8-AFC4-AB702511C276}

That's an informational security message and nothing else, in general. Would you consider it a problem if you received reports that people can't access your documents on your computer?

Now, if someone is a colleague and should have access, that's a different story.  Try and resolve the problem through the misbehaving application, if there is any at all, in other words. Did you notice that Cortana can't index your documents, in the search results, for example? File a Cortana bug report in that case.

She's doing it quite well indexing mine. In fact, this is the first I've heard of the issue.

I've been ignoring most of the posts here, because the discussion has strayed from factual problems to unrelated areas.

BUT LET'S GET BACK TO BASICS.

The issue here has nothing to do with indexing or accessing documents on your PC.

What is involved is an internal denial of access to subunits of one's installed applications to the resources needed to complete their designated task(s).  This is what produces "hangs" and program failures that seem confined to certain interactions with only SOME programs, while other interactions complete without problem.  The permissions vary with both the initiating program AND the target program.

This worked for me, no more error messages in Event Viewer.

No it didn't errors return 2 days later.
