In case it has relevance, the laptop (Gateway NV79) came with Win7 Home Premium preinstalled and it was upgraded to Win 7 Pro with a Windows Anytime Upgrade key purchased from Microsoft. I contacted Microsoft 3-4 months after such version upgrade when I got the SP1 installation error message for the first time, but received no help whatsoever. Any informed suggestions on how to fix this problem, so I can finally install SP1? TIA
