'iTunes.msi' not found

The same thing happened to me...I can't update my ITunes or Quick Time. I also get the same error for QuickTime.msi as well. Did someone ever reply to this?

Waiting patiently for a response to this as well. I'm about to purchase a a touch for a birthday present and it would be great if this problem resolved beforehand.

I was going to manually delete and start over, but I have a TON of purchased music I don't want to lose/re-buy.

I'm having the same problem - I've spent my entire morning trying to fix/troubleshoot it with no luck!

WHen you get msi problems, the Microsoft Installer Cleanup Utility usually fixes it.

Here is a full method:

== uninstall with cleanup ==
Download a fresh copy of iTunes and the stand alone version of Quicktime (the one without iTunes)

http://www.apple.com/quicktime/download/win.html
http://www.apple.com/itunes/download/

Save the files on your PC.

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. The installer doesn't give any message to confirm the installation.

(To run the program – All Programs>>Windows Install)

Now use the following method to remove iTunes and its components:
XP

Vista

*If you hit a problem with one of the uninstalls don't worry*, carry on with the deleting of files and folders as directed in the method.

When you get to deleting Quicktime files in the system32 folder as advised in the method, you can delete any file or folder with Quicktime in the name.

Restart your PC.

Run the Microsoft Installer Cleanup Utility. (Start > All Programs > Windows Install Clean Up)

Remove any references you find to the programs you removed - strictly speaking you only need to worry about those programs where the uninstall failed.

If you don’t see an entry for one of the programs that did not uninstall, look out for blank entries or numeric entries that look like version numbers e.g. 7.x for Quicktime or 1.x for Bonjour.

restart your PC

Install the stand alone Quicktime and check that it works.

If it does, install iTunes.

Polydorus, your instructions worked for me except I still could not uninstall ITunes or Quick Time using the ADD/REMOVE SOFTWARE menu in control panel. I had to manually remove all ITUNES and Quick Time files in the programs common files folder as well as go into the Regedit and manually delete all ITunes and Quick Time files. Then I restarted my PC, then I installed the MS Install Clean Up program and ran it to remove ITunes & Quick Times files, then I rebooted again. Then I installed Itunes alone. I haven't decided if I'll install quick times yet. If I need it I'll install it but I don't use it so I probably won't. I hope this helps others.

ITunes needs to address this problem with their updates. I don't want to go through this everytime I upgrade. I just may not upgrade any more versions if they don't get their act together.

If you installed iTunes, then you installed Quicktime. It is part of the iTunes install and you cannot avoid it as iTunes will not run if Quicktime is not installed as it uses Quicktime in order to play content.

The separate installation of Quicktime is simply there in the method because occasionally installing Quicktime first helps with iTunes installation problems.

a thousand thanks. problem solved.

Thank you so much for your help Polydorus! It worked like a charm 😀

Brilliant! Thanks for the great instructions. My problems are fixed.

I have the same problem with a twist.. I installed the new 3.0 OS and after I installed it I lost my entire Music library. I tried to reinstall it by syncing with iTunes but I get the error message that I need to install iTunes 8.2.1. When I try to update to 8.2.1 I get the error message as originally described. I'm afraid to try the fix as described by Polydorus for fear that I may lose my music (907 songs) if I do. Any help would be most appreciated. Thanks.

I also have a similar problem. I have tried to install the new versions of itunes for the past 5 months and every time I have installed them and I have gone on to itunes it says "itunes was not properly installed. If you wish to import or burn CD's, you need to reinstall itunes." I have reinstalled itunes on a number of occassions and have also done what is mentioned above to no success. I would be very grateful for any help at all.

I'm considering a visit to the local Apple store to see what they suggest. I will post my findings after I visit.
