hello experts, i've deleted my office 2010 software because i repeatedly got error message: 0xC004F056 . i first used "revo uninstaller pro", then i used the "microsoft cleanup utility", after which i went manually to check the registry and each time it was mostly clean except for the registry folder "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office". every time i try to delete it or any of its subfolders and keys i get this message: "cannot delete office: error while deleting key". i tried playing around with permissions hoping it might work, but it didnt. i tried leaving it there and reinstalled my office software (at least 3 times), but i still get the 0xC004F056 error message. i must get rid of it - so please your advice. thanks.
