I tried to install SP1 to Windows 7 pro 64-bit and got error code 0X800F0805. After installing tried System update readiness tool and update SP1 again. WU says installation success, but I cannot uninstall SP1 and still can install it. Still got same error code after installing System update readiness tool. Tried also turning AV off, but it did not help. So what to do now?
And CBS.log says 2011-02-23 12:54:20, Info CBS Failed to internally open package. [HRESULT = 0x800f0805 - CBS_E_INVALID_PACKAGE]
