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}
