Upgrade from Backup disc not possible?

I bought an upgrade to Windows 7 Home Premium (from Vista 64) via the store, downloaded the upgrade file - geez thats a big one :) -  but could not install it kept coming up "crc error".  Tried a couple of times to download again, but always ended up with crc error when running the file. So I thought, ok, wait for the backup disc in the post.  The latter arrived today (took two weeks).

Put that in the dvd drive, an up comes an error message (contained in a txt file) claiming it cant install from dvd unless the op sys supports ISO13346 UDF file system spec.

I am assuming that translates to the fact that the back up disc will only work (in terms of op sys install) if Windows 7 is installed.  If I am correct, and I am posting this to check my assumption, then it looks like I must go back and fight the good fight on clean download of the original upgrade file (I've tried many ways including download managers).

The catch 22 of a op sys install backup disc that will only allow install if the op sys is installed is worthy of Monty Python, you couldnt make it up ....  :)

Anyway, having allowed myself a mini-winge .....  grateful for advice as to whether or not I need to hit the download route again, or if in fact I am making a basic error somewhere.

Phenom2 8Gb  1Tb disc (currently has Vista 64), checks out ok on upgrade advisor, all "green"

Any advice/assist gratefuly received.

Wow, that was incredible :)

I finally managed to get a clean download of the Install files, they unpacked well, and the upgrade routine started.

Having suffered Op Sys installs since Windows 3 first came out in 1990, it was with a feeling of some trepidation ......  all the Op Sys changes for the last 20 years had fallen over when doing the initial upgrade to a new Version, resulting in nightmares, every-single-time ....... until now.

This went like a dream.  It was an Upgrade install - not clean install - over a Vista64 installation.  Took 90 mins overall, slick and easy.  All programmes transfered across no trouble, no hours of programme installs ....  I have a lot on the beast, all in no messing, no reinstalls, very impressed.

A dose of Humble Pie eaten this end.  Well Done to the Devs, you turned a Doubting Thomas into a raving fan of MS installs again, no mean feat after my 20 years of "Upgrade Nightmares".

This thing has my Vote already and I have not started to use it as such yet.

Nice One .... Well Done Guys ....  *bows and scraps in humble thanks*  :)
