Administrators AWS Posted January 17, 2013 Administrators Posted January 17, 2013 I am running HP Pavilion p6740f Desktop with Windows 7, 64bit, Windows Home Premium. I have never had trouble with using Windows Update. But today I have attempted to install a Windows Update [actually two] and I am getting the same results...failed. I have done nothing that would account for this problem. I did repeat the attempt to download updates several times...failed. In the fail message it says ERROR 643. I also went online to see if anyone, in google, had this same problem. Several people did, but they don't have a solution. I need some help. Thanks, Joseph View this thread
