Can't upgrade past v7.6.2.9-

Question

I'm posting this here in anticipation that I won't actually hear from Apple. I sent them the same thing below. Let me know if you have any thoughts!
I can not get my shows purchased from iTunes Store to show up under my ‘TV Shows’ on iTunes. Let me give you a background:
I've been on iTunes 7.2.6.9 version, then got the notice to upgrade to 8.2 and really put it off for about a month. So I ended up downloading the 8.2 software. The install started but then I got this message shortly after the installation started, "There is a problem with this window installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor."
So, I back out of the installation. Following the six bold steps found on the following troubleshooting page (http://support.apple.com/kb/HT1926) I am still unable to upgrade to 8.2. I even went as far as booting into Safe Mode and removed iTunes and other said files in the troubleshooting steps, but no luck. I've even used the MS Uninstaller to remove iTunes then tried installing 8.2, no luck, again. I even searched out new versions than my 7x but less than 8.2 and tried to install 7.7, 7.7.1, 8.0 and also 8.1 and I get the same error message as I mentioned above for all four! But as soon as I re-installed 7.6.2.9, no problem with installation!
So, I decided to reinstall Ver. 7.2.6.9. After figuring out how to move the iTunes Library.itl file from the previous version (which couldn't be read because it said it was from a newer version) I had to take an older version and repopulate ALL covers to my library! Matter of fact, the "Get Album Artwork" doesn't even work now! That’s how I’ve populated all my albums before. Even with the most popular or old albums iTunes tells me that no artwork can be found (which is a joke because out of 160 albums without covers, it couldn't find not one!). So, if you know why that's not working, I'd like to hear about it and how to fix it. Because, I then had to go out to Google Images and search for ALL 160 albums, take screen shots and update the album info by importing the image. That was ridiculously time consuming. But I digress...
Ok, now that I've re-established all album covers (on my own) I'm finding that none of my TV Shows that I purchased via iTunes Store have been populated. So, my first attempt was to "Add Folder To Library" thinking that if I just point to the ITUNES/TV SHOWS folder it would populate all that’s in there. Well, it pops up with the 'Processing' window and I see it reading each of the TV Shows, but then the window just goes away and nothing more. No shows appeared in the TV Show folder of iTunes Library. So, I try, "Import...", no luck there either. Next, I try, "Add File To Library," thinking I'll have to go the long way around and import one at a time (another ridiculously time consuming step). But, I couldn't even get that far. After selecting the file, nothing happens!
Then I thought I could move the TV Shows from the iPod back to iTunes by way of, "Transfer Purchases from 'name of iPod.'" Well, it read the iPod but didn't notice anything different on iTunes if it actually transferred anything. If it did transfer those files purchased, where does it put them?
So, now I'm at a loss. My first issue is I can't even upgrade to 8.2 (let alone to 7.7), which I suspect would solve all these problems. But I can't even get the install to fully work. I have taken a WMV of the steps of the installation in the event anyone wants to view it to see what I've described above. If you know of the error mentioned above and knowing that I've done all the troubleshooting steps the site recommended what would you recommend? In the past, the only thing I've had to do when upgrading is simply remove iTunes. But this time around, not even uninstalling the current version works with installing the new version.
Now, I have TV Shows on my hard drive but iTunes won't process them correctly to show them in the Library. Why? I can't figure it out. So, given I have tried all option under the FILE drop down in iTunes, I am at a loss. I only come to those of you who use iTunes and are more familiar than I am. But again, maybe one of you can provide support on the grand problem of upgrading to 8.2 which may or may not solve the problem of the TV Shows.
Thanks

+"There is a problem with this window installer package. A program run as part of the setup did not finish as expected. Contact your support personnel or package vendor."+
This message often relates to a problem with Apple software update.
Go to Add remove programs and find Apple Software update. Try repairing it.
Select Change>>repair.
If that works, try installing iTunes.
Otherwise try uninstalling any instance you find of Apple Software update. That probably will not work if repair didn't.
Next try an installer cleanup.
Download and install Microsoft Installer cleanup utility, there are instructions on the page as well as the download. Note that what you download is the installer not the program – you have to run it to install the program.

To run the program – All Programs>>Windows Install Cleanup
Remove any instance you find of Apple software update with the cleanup utility.
Download a fresh copy of the iTunes installer and save it on your desktop.

Restart your computer and try installing iTunes
