At the time I open windows update it shows me that update KB973688 and KB954430 are failing to get installed. These are not shown in the control panel as installed updates on programs as they will not get deleted and reinstallation is not also possible because in the 1st lay they are never installed. Windows Update shows that’s error code 643.
I have tried to update windows by manual ways but after clicking run I got this message which is: "Error opening installation log file. Verify that the specified log file location exists and is writable." I got totally new Sony Vaio and Windows 7, 64 bit and I don’t know how to solve this. Please help me out to solve it.
Thank you in advance for your cooperation
