Hi Gerry
I have already been down this route. I tried an upgrade re-install using my Windows 7 Professional 64 bit SP 1 disc bought with hard earned cash from Microsoft. I cot an error message during the file copying stage that some files were corrupt. Error 0x80070241.
I downloaded the same operating system, Windows 7 Professional 64 bit SP 1 from Digital river, burned a copy onto a DVD at the slowest speed settings and got exactly the same response
I downloaded Windows 7 Professional 64 bit SP 1 again and placed it on a separate drive to C:. I downloaded 7-zip and unzipped it to exactly the same drive and got exactly the same failure at exactly the same point exactly the same error code 0.x80070241.
I downloaded another fresh copy of Windows 7 Professional 64 bit SP 1 to another drive and unzipped it to another drive (downloaded to e:\ (different disc) and unzipped to F:\ (same disc) and yes I got the same result at the same point error code 0x80070241.
I have downloaded to both internal drives. I have used the same drive and I have used the other drive when extracting and the result is exactly the same.
I looked up the error message on Microsoft's website. Nothing official but a lot of chatter from disgruntled customers.
So after all this time and messing around I am no further forward. Microsoft really don't give a tinkers toss. I bought Windows 7 Professional 64 bit because I wanted to use my pc. Not so that I could spend all my time trying to get the OS to work properly.
If I sound ungrateful Gerry then I apologise. It's not your fault, I mam sure you are a very capable and very nice guy. But if Microsoft don't give a toss you are as screwed as I am. Come over to Linux, I'm going the Ubuntu route. I have it running like
a dream on another pc with all I need, including Libre office for free.
