Failed install for Security Update for .Net Framework 4: KB 2726428, KB2742595, KB2727019 and KB 272

[AWS]

Hi Folks,

I get error code 643 (unknown error) reported when the system tries to install Security Update for .Net Framework 4: KB 2726428, KB2742595, KB2727019 and KB 2729449. This has been happening for several weeks as the system tries to update immediately following

shut down. It always fails and takes around 75 mins to fail. I’ve tried running each update individually, also without success. I’m also suffering a lot of “grey screen” where all windows become unresponsive for several minutes and I eventually turn my laptop

off at the power switch. I have McAfee Real time scanning, Firewall and anti spam etc all switched on and I also have MSE Security Essentials loaded – perhaps a conflict? Any ideas? I’m using W7 Home Premium. Thanks and regards, Nigel
