Application-specific permission settings error

Question

I get this error pretty frequently. It will lock my machine up for about 30 sec. Mouse and keyboard stop working, then the screen goes blank, and after a few more seconds everything comes back. Here is the rest of the error.

---

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 MERLIN\Drew SID (S-1-5-21-4046456677-2726157511-2513478225-1001) 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.

I'm pretty good with PC's. Been working on them since DOS 5.0. These deeper dives though, got me scratching my hair.

Appreciate any help.

Hi,
This is a DCOM error, which is normal. This has nothing to do with the lock-up.

Please test in Safe Mode and let me know.

Please open the Windows Recovery environment using either of the steps below:

On the Lock Screen, Press and hold the Shift key. Then, click the restart button on the lock screen located at the bottom right situated in the Power menu, to open the Windows Recovery options.

If you cannot reach the Lock screen or start your computer, restart your PC two times when the boot screen is shown. If your PC has no restart button, press and hold the Power button until the computer shuts down. Do this twice.

On the third time, windows should open Windows Recovery options automatically.

In the Windows Recovery menu,

Select the Troubleshoot option.

Then, select Advanced Options.

Click Startup Settings as the next step.

Click the Restart button.

Click five or F5 to Start the computer in Safe Mode with Networking.

I’m eager to hear back and work together to find a solution.

Hi @Drew89521

For your pc issue not because of the application-specific permission settings. the same error i received in my system as well. may be cause of OS corrupted or any hardware related issue. just first try to do some scanning .

• Goto Run then type sfc /scannow. once scanning done then restart your PC. then monitor the same issue will occurred or not suppose repeated the same you need to reinstall OS. suppose same repeated after reinstall then you have to check hardware's like RAM/Motherboard/HDD/SSD issue.

Thanks.

The error indicates a COM security/permissions problem for a specific COM server (identified by CLSID and APPID) and user account. The message states that Local Activation permission is not granted, and explicitly says that this security permission can be modified using the Component Services administrative tool.

To address this kind of issue, the supported approach in the provided context is to adjust COM security permissions through Component Services, similar to how SELF or other groups are granted access for COM/DCOM scenarios:

1. Open the Component Services MMC:
   • In the Search box, type dcomcnfg and select Component Services.
2. In the left pane, expand Component Services > Computers.
3. Right‑click My Computer, select Properties, then go to the COM Security tab.
4. Under Access Permissions or Launch and Activation Permissions (depending on where the restriction applies), use Edit Default or Edit Limits and ensure that the relevant account or group has the required permissions (for example, Local Access/Remote Access or Local Activation/Remote Activation), following the same pattern as for the SELF or Certificate Service DCOM Access entries in the context:
   • Add the account or group if it is missing.
   • Grant the appropriate permissions (e.g., Local Access/Remote Access or Local Activation/Remote Activation).
5. Select OK to close the dialogs and then restart the computer so the new COM security settings take effect.

When adjusting COM security, only change the specific entries needed for the failing component or account. Broad or incorrect permission changes can weaken security or cause other components to fail.
