Unfortunately b noir is around much just now, I am not sure if this will help you but here are links to help about the Windows update error numbers

When you say you "tried those but it still doesn't work", do you mean that they did not fix your windows update problem, or that they did, but iTunes still wouldn't install.

The iTunes VC80.CRT errors associated with update failures are caused by Windows problems which are fixed by fixing the Windows update problem and installing all the outstanding updates.

I think it is important to get Windows update fixed before worrying about iTunes.

Added: actually I realise that I am assuming that you have a VC80.CRT error, is that correct?

Also Here is a link to a b noir thread with this error in case you haven't found it.

I think there is one thing that ought to be got out of the way and that is malware.

Try running a full scan with the free version of Malwarebytes:

At the bottom of the page on 80246005 you are referred on to:

In order to request help by email, I don't know if this would be productive, but it might be worth a go.

I see that b noir seems to be posting again so maybe he will join in.

Hiya. polydorus asked if I could stop by.

Working on the principle that usually the Windows Update error message often gives a truer account of the underlying cause of things than the iTunes install error, I'm still thinking we might have an issue with the catroot folder.

As well as permissions or things like read-only settings, disk/folder damage might conceivably be stopping files from writing to the folder. So I think we'd better try a disk check (chkdsk) on the C:\ drive.

There's Vista instructions in the following document.

[Check your hard disk for errors|http://windows.microsoft.com/en-us/windows-vista/Check-your-hard-disk-fo r-errors]

Select both Automatically fix file system errors and Scan for and attempt recovery of bad sectors. You'll probably need to schedule the scan to run on restart. The disk check should take quite a while to run (if you're running it on the C). If it quits after a few minutes or seconds, something's interfering with the scan.

Does the disk check find/repair any damage? If so, do your windows updates start installing again?

Corefoundation.dll is a component of Apple Application Support.

A quick thing to try:
Go to Control Panel Programs and find Apple Application support and select repair, You can also access repair by right clicking in the program. I don't remember offhand if Vista and Windows 7 look the same.

If it doesn't work, try disconnecting from the internet then disabling security software while trying again.

However now when I restart the computer it comes up with an Apple Syn Notifier.exe error message about being unable to locate a component because the Core Foundation.dll was not found. I assume this is to do with apple itunes.

That one is actually the MobileMe control panel acting up ... another Apple program that uses Apple Application Support. In most cases the messages on startup are related to an out of date MobileMe version not working well with a higher version of AAS, but in this case it's probably being produced because AAS isn't actually installed at the moment. To get rid of the messages on startup in the meantime (until we can get AAS installed), uninstalling the MobileMe control panel should do the trick.

Back to the iTunes/AAS/Updates install issues. Could you walk us through what happened when you ran the sfc /scannow? Did the scan go through okay, or did you get an error message instead? If you got an error message, what did it say?

Okay ... sounds like there's nothing amiss with the sfc, but it just isn't touching the source of our problem.

Thoroughly experimental stuff now, so I'd consider perhaps getting a second opinion prior to proceeding.

I'm still concerned about the catroot2 folder. If it's damaged in a way that chkdsk doesn't recognise, then renaming it might be the way to go. I'd try *2. Rename the Catroot2 folder* from TaurArian's post in the following thread at Microsoft Answers:

[SP2 error code 80242016-will not install|http://social.answers.microsoft.com/Forums/en-US/vistawu/thread/d0ad1b6 1-2b90-4c2f-9fdc-5db63fca4ec4>

Excellent question. According to all the literature I can track down at Microsoft about it, if there isn't a catroot2 folder, Windows automatically regenerates the folder. (The same does not go for the catroot folder, so be careful not to rename that one instead.)

If a new catroot2 isn't regenerated, name the old one catroot2 again. (So, say, call the other one catroot2OLD, and if all does not go according to the literature and a new catroot2 isn't generated, just drop the OLD from the name to get the catroot2 folder back.)
