Apple solution to iTunes install problem - More needed from Apple

Question

Apple has published a fix for the problem arising from attempts to install the latest iTunes upgrade at http://support.apple.com/kb/ts3074.
In it they suggest the issue may be caused by a bad installation of a version of Microsoft's .NET Framework.
Find this somewhat preposterous for the simple reason that all was well until the attempt to load the new upgrade of iTunes.  For Apple's suggestion to hold true it can only mean that none of my other applications make any use of MS.NET Framework, which I very much doubt.
Performed the fix for Windows7 prescribed by Apple, namely downloaded and ran Microsoft's .NET Framework taking the 'Repair' option when prompted. When Repair completed successfully you have to shut down and restart Windows to make the repaired software available.  Did this and on restart lo and behold the R6034 message appeared again.
Did a search of the Registry for 'R6034' but not found.
Being unsure what was issuing the message deleted iTunes and restarted the system.
Again lo and behold the R6034 message appeared again.
Fortunately had been away from my computer for several weeks, and as the only upgrade actioned since my return was for iTunes carried out a System Restore.  This got rid of the R6034 message, everything worked fine, and when I shut down Microsoft automatically reinstalled all its upgrades after the Restore point.
Then moved to put back the iTunes upgrade prior to the current one.  ITunes stopped me in my tracks by halting the reinstall because "A later version of the program had been installed". Presume this was because iTunes detected from its records that I had actioned the latest upgrade
As I see the iTunes upgrade as the problem, I'm hoping firstly that someone from Apple will read this and:
1     provide more support than it has to date; and
2     allow those who want to pass on the upgrade reinstall the previous version of ITunes.
Cheers.

Intresting notes... When you download album artwork from iTunes it really doesn't add it to the MP3 track, it stores it elsewhere and assoicates it internally some how to the album. Where as adding a artwork in through the actual file will change the size of your MP3 track, by embedding the artwork into it so that other apps (like windows media) can see them.
That would be an interesting find if that is indeed the case.... Furthermore if that solves the problem, than apple should have an easy fix on thier hands.
However, since most of my music is direct downloads from iTunes and has the artwork directly embedded into the music files like I mentioned above that might be why I've never encountered the issues.... As I found out about this quirk a while back, because some of the tracks on the PC or on my iPod would never show the album cover before...
Hopefully someone else with the same problem can help confirm this possible solution!
