On the Permissions tab in the Advanced Security Settings for WMPTheme.WMPSkinMngr dialog box, for the user who is currently signed in to the computer, make sure that Full Control is listed in the Permissions column.

What to do if the Group or user names list is empty

If the Group or user names list is empty, you can work around the problem by renaming the registry key HKEY_LOCAL_MACHINE\Software\Classes\WMPTheme.WMPSkinMngr\ as HKEY_LOCAL_MACHINE\Software\Classes\WMPTheme.WMPSkinMngr.backup\. After you rename the key, rerun the Zune Software installation.
