Windows Error 2 when trying to download iTunes 9 - HELP!

Do you have a 32-bit or a 64-bit version of Vista, Amy? (That makes a different to how we go about fixing an error 2, because the program files for iTunes and Apple Application support live in different places on a 64-bit system than they do on a 32-bit version.)

If you're unsure, this document may be of some help:

Hi, I am on a 32 bit version.
Same error 2 problem. I was originally having the error 7 problem, but after uninstalling mobileme, the error stopped. I get the error when installing itunes, then it does the "rollback action"
Please help. I am so frustrated with this.

This won't help you but I have exactly the same problem and haven't yet resolved it (see my question can't intall new version of itunes or quicktime).

I get the error when installing itunes, then it does the "rollback action"

Do you get an error 2 when installing iTunes, or just when trying to run it after the install, Jamez? If you're getting a different error during the install, what does that one say?

Hi b noir:
My exact error I get when installing iTunes prior to the rollback action is as follows:

An error occurred during the installation assembly 'Microsoft.VC80.CRT,version="8.0.50727.4053,type="win32",publicKeyToken="1fc8b3 b9a1e18e3b",processorArchitecture="x86". Please refer Help and Support for more information. HRESULT: 0x8007054f.

Thanks for your help.

HRESULT: 0x8007054f.

... that seems to have been the most popular alphanumeric code in recent days. (Just like katherine's one.)

In general, these ones tend to be caused by underlying problems on the PC that can prevent Windows Updates from installing. So my main strategy with them is to try to fix the Windows Update issues. If we can get Windows Updates flowing again, that generally clears up the iTunes install errors +en passant.+

Head into your Windows Update, and check for any new updates. Do any fail? If so, open your Update History and doubleclick on the failure entries to bring up a small box with alphanumeric error message codes. Are you getting 8000FFFFs? (They often seem to be associated with an iTunes-install 0x8007054f.)

If you're getting 8000FFFFs, try the following Microsoft document:

[Windows Update Error 8000FFFF|http://windows.microsoft.com/en-US/windows-vista/Windows-Update-Error- 8000FFFF]

Head back to Windows Update, and see if you can get Updates to install successfully this time. If you can get updates now, stock up on any updates you're behind on. Once you're completely up to date in that regard, try another iTunes install. Does it go through properly this time?

i just got my new laptop today, and i tried installing itunes 10 on it. it keeps showing the "Apple application support is not found" window. this is after i have installed itunes. any suggestions??

Dear Noir
I get the error 2 message everytime I click on the Itunes icon and also AFTER I reinstall the installer. Do you have any advise on the problem I'm experiencing??

THanking you
Nadia

P.S. I've tried install iTunes10 although my computer previously had another version (not sure which). Should I try to reinstall the one I had?

I get the error 2 message everytime I click on the Itunes icon and also AFTER I reinstall the installer. Do you have any advise on the problem I'm experiencing??

Hmmm ... if you've got the checkbox checked to launch iTunes immediately after the install completes, then the 2-after-install might just be another 2-when-launching, nadia.

Give us a few moments, and I'll show up in your topic to have a look at your situation there.
