I have a problem with Windows 8.
Something blocks any access to any subkeys of
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EventLog. As a result many applications can't be installed.
I can see the list of those subkeys but cannot access them in any way. When I click on a subkey, a message pops up indicating that the key cannot be opened because of an error,
I also can't edit the
Security Settings of the keys because of the same message.
I had this problem two days ago and I re-installed my OS. This fixed the problem, but after a day it occurred again. I have the following applications installed: Office 2010, VS2012, WebMatrix, Avast! Antivirus, Google Chrome and Google Picasa.
I've uninstalled Avast, but the keys were still blocked.
