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

Hi, my name is Kelly, and I'm an independent consultant and I'm here to help.

Based on the error message you provided, it seems that the problem is related to permission settings for a COM Server application. You mentioned that you have already tried modifying the permission settings in both regedit and dcomcnfg, but the problem persists.

Here are a few additional steps you can try to resolve the issue:

Run Component Services as an administrator:
Press the Windows key + R on your keyboard to open the Run dialog box.
Type "dcomcnfg" in the Run dialog box and press Enter.
In the Component Services window, right-click on "Component Services" and select "Run as administrator."
In the left-hand pane of the Component Services window, expand "Component Services" and then "Computers."
Right-click on "My Computer" and select "Properties."
Click on the "Default Properties" tab and make sure that the "Enable Distributed COM on this computer" checkbox is checked.
Click on the "COM Security" tab and under "Access Permissions," click on "Edit Limits."
Make sure that "ANONYMOUS LOGON" is listed and has "Remote Access" and "Local Access" permissions checked.
Click on "OK" to save the changes and close the window.
Reset the permissions for the COM Server application:
Open the Registry Editor by pressing the Windows key + R on your keyboard, typing "regedit" in the Run dialog box, and pressing Enter.
Navigate to the following key: HKEY_CLASSES_ROOT\CLSID{2593F8B9-4EAF-457C-B68A-50F6B8EA6B54}
Right-click on the {2593F8B9-4EAF-457C-B68A-50F6B8EA6B54} key and select "Permissions."
Click on "Advanced" and then on "Change Permissions."
Make sure that the "Include inheritable permissions from this object's parent" checkbox is checked.
Click on "OK" to save the changes and close the window.
Run a malware scan:
Install and run a reputable anti-malware software to scan your computer for any malware infections that may be causing the issue.
If none of the above steps work, you may need to seek further assistance from a professional technician or support from the software developer.
