Apple Application Support won't install

I can't get the new itunes upgrade to install. I tried the update, that didn't work. So I unistalled itunes and quicktime thinking this might help. It didn't. I've tried everything the support says and it still won't download. I then downloaded only and when I go to the "open downloaded files" from the tool bar from the apple software update window, I click on the apple application support and I get this error:

An error occured during the installation of assembly 'Microsoft.VC80.............................HRESULT: 0x8007054F

I can install the itunes and quicktime from the update window, but without the application support, i can't do anything with it. Please Help!

I'm using Vista and running Internet Explorer if that helps.

Dell Studio, Windows Vista

Drat.

Excuse me for the delay, aid8m but I've had to do a bit of a re-read of the thread. I've been simultaneously doing a troubleshoot of a 0x80073712 variation of this business with jaiden today (iTunes, sundry Windows Updates and Vista SP1 installs are coming to grief for her), and I'm beginning to struggle to keep straight on what we've been doing in each thread:

Okay ... I've had a different thought about getting into the sfcdetails.txt on your system. Rather than fiddling about with the environmental variables to get edit to operate from the command line, try checking through your system32 folder and seeing if you can track down the sfcdetails.txt file. Then just doubleclick on it and let whatever application opens .txt files by default on your system open it.

Can you paste a copy of the contents of the file into a reply here?

Okay, this is getting a little frustrating. i found sfcdetails.txt, but it is 0 kb and empty. I ran the scan again, and got the same message:

Beginning verification phase of system scan.
Verification 100% complete.
Windows Resource Protection found corrupt files but was unable to fix some of them.

I opened up the cbs.log to try and find the problem. I tried to find the phrase "Cannot repair member file", but it apparently does not even contain the word "cannot".

I'm really not sure what is going on.

Damnit. It sounds like the sfc runs might be failing altogether. So Windows can't find the edit commamd, and sfc is messed up too.

Let's try another track. The other idea I was thinking about earlier on was that this could be some kind of subtle permissions issue. If that's the case then iphone3Gguy's idea about making a new user account (with full administrative rights) and attempting the iTunes install from inside there may get us moving further forward.

Can any of the Windows Update, the security update, or iTunes install from inside the new user account?

Another note to anyone reading this in the future:

I originally followed Apple's suggestion that I uninstall iTunes then try to re-install the latest version. Since the latest version wouldn't install, I have been without iTunes for a few days.

However, I downloaded 9.0, which was the version I was using before. It actually installed perfectly and has given me an at least semi-functioning version of iTunes for the time being.

That's interesting, aid8me ... so the install is going bad for the 1.1.0 version of Apple Application Support, but not the 1.0.1 version of Apple Application Support.

... What security software are you running on that PC? (Firewall, antivirus, antispyware?)

Even if it isn't currently installed, has a Symantec security product (like Norton) *ever been* installed on the PC?

Sorry about the delay aid8me. I've been dwelling on how best to proceed next.

I think we'll try first treating this as if it we were treating a more-standard sort of Apple Application Support installation error where we suspect security software interference on the install. If no joy with that, we'll work up to a more aggressive set of treatments.

Best to print out a copy of these instructions, because at one point of proceeding you won't be able to use a web browser.

Preliminaries

Download and save a fresh iTunes installer to your hard drive. (Don't run the install on line and don't start the iTunes install just yet.)

http://www.apple.com/itunes/download/

Now, quit QuickTime (if you have that open) and Safari 4.0.4 (if you have that installed and open). Both applications use Apple Application Support, and they will interfere with the uninstall if you have them open.

*Uninstall phase*

Head into your "Uninstall a Program" control panel. Uninstall iTunes. Uninstall Apple Application Support.

(From this point on until we reinstall Apple Application Support, neither QuickTime nor Safari 4.0.4 will be able to run.)

Next we'll remove any leftover program files and folders.

(1) Open "Local Disk (C:)" or whichever drive your program files are stored on.
(2) Open the "Program Files" folder.
(3) Right-click on the iTunes folder (if it still exists) and select "Delete".
(4) Go back to "Local Disk (C:)" or whichever drive your program files are stored on.
(5) Open the "Program Files (x86)" folder
(6) Right-click on the iTunes folder (if it still exists) and select "Delete".
(7) Staying in *Program Files x86,* open the "Common files" folder.
(8) Open the "Apple" folder.
(9) Right-click on the Apple Application Support folder (if it still exists) and select "Delete".

Now empty your Recycle Bin and restart the PC.

*Reinstall Phase*

After the PC restarts, *do not* open any other applications. Disconnect from your network and/or the internet. Switch off all your security software (firewall, antivirus and antispyware).

Now start the install by doubleclicking the iTunes64Setup.exe file you downloaded earlier.

Reenable all security software prior to reconnecting to your network and/or the internet.

Did the install seem to go through okay? Or do we still get the same sort of 1935 error on the Apple Application Support part of the install?
