Hi, I have tried to install SP1 on Window 7 Home Premium x64 several times today and all end up with failure with the same error code. (error code 0x80073701 - the reference can not be found). I have tried troubleshooting windows update, system update readiness tools, disabling security software, and even installing in safe mode, and all end up with failure. I use offline installer (windows6.1-KB976932-X64.exe) because using windows update, the download can't even start (at first, it starts, then stuck at 22%, and then it shows the same error code).
Hope you can help...
Firewall: Windows Firewall
Antivirus: Microsoft Security Essential 2.0
Additional security softwares: Malwarebytes Anti-Malware 1.50 with real-time protection (has been disabled, but still fail), Panda USB Vaccine (I think this has no connection at all with this problem)
Additional resident programs: SmartDefrag 1.5, Advanced SystemCare 3.7.3, Daemon Tools Lite
