The application-specific permission settings do not grant Local Activation permission for the COM Server application with CLSID {61738644-F196-11D0-9953-00C04FD919C1}

to the user DOMAIN\svcspdev SID (S-1-5-21-3914637029-2275272621-3670275343-1145) from address LocalHost (Using LRPC). This security permission can be modified using the Component Services administrative tool.

To rectify this error, first you need to do this on the SharePoint server - Windows Server 2008 R2. You must first take ownership of the corresponding registry key and grant Administrators permissions to update the configuration. If you do not take the ownership and try to add the user, pop-up window will appear and will say “ACCESS IS DENIED”

To grand permission to the configuration of the IIS WAMREG Admin Service to be changed using the Component Services console:

1. Click the Start menu, type regedit, and then click regedit.exe.  If prompted by User Account Control to allow the program to make changes to this computer, click Yes.
2. In the Registry Editor window, search for the CLSID “61738644-F196-11D0-9953-00C04FD919C1″ to find HKEY_CLASSES_ROOT\AppID\{61738644-F196-11D0-9953-00C04FD919C1}.
3. Right-click on the HKEY_CLASSES_ROOT\AppID\{61738644-F196-11D0-9953-00C04FD919C1} key and then click Permissions.
4. In the Permissions for {61738644-F196-11D0-9953-00C04FD919C1} dialog box, click Advanced.
5. In the Advanced Security Settings for {61738644-F196-11D0-9953-00C04FD919C1} dialog box:
   1. Click the Owner tab.
   2. In the Change owner to list, click the Administrators group.
   3. Click OK.
6. In the Permissions for {61738644-F196-11D0-9953-00C04FD919C1} dialog box, click the Administrators group, then click the checkbox to allow the group Full Control, and click OK.
7. Close the Registry Editor window.

Now you have granted the Administrators group to sufficient permissions, now how to change the IIS WAMREG Admin Service. If you don’t do the previous step and go directly to the component service, all the fields are disabled.
