iTunes 10.4.1 install failed

What I learned from my experience with 10.4.1 is that there seems to be conflicting information that is held in temporary files in Windows that creates a propblem with this particular update.

I did a lot of trial and error and I an NOT an expert so all I can suggest is listen to the advice of those that are and clean out your temp files.

Interestingly what finally worked was the last download from the Apple website that when loaded and working was 10.4.10. Does that make a difference - I don't know.

Correction - what I downloaded and installed satisfactorily is iTunes 10.4.1.10. Works fine. Do note it is a different version than the program that caused the initial conflict. Perhaps Apple tech solved the issues that caused the initial problem.

Many thanks! worked for me. Followed your suggestion and made the permission changes to the respective registry folders named in error msg. sincerely hope that the others have worked this issue out by now. It can be really frustrating when such trivial issues cost so much time. Thanks again mate!

I've been trying for a couple weeks to update my iTunes to version 10.4.1.10 with no success. So, I just went to the iTunes site and downloaded it from there (NOTE: without uninstalling my previous version), and it worked!?!

I did the same..downloaded the iTunes 10.4.1.10 from the iTunes site, and it installed successfully.

I have problems updating itunes 10.0 to 10.4.1 automatic process abort and manual process said "It is neccessary to install Quicktime" but Quicktime has been always installed. What should I do?

I have had exactly the same problem - an "error occured", "install manually" (which failed too) and "it's neccessary to install Quicktime" which I have had for ages!! I tried MANY times.

But today I went to http://www.apple.com/dk/itunes/download/ and I could see that they now have two different download choises of 10.4.1 - and since my PC is 37-bit, I chose the first one for Windows XP, Vista oe Windows 7 (which I have) and then I downloaded iTunes - without uninstalling anything first!! The downloaded version is 10.4.10 and it works perfect!!

Try that and good luck!

Thanks. I follow your indications getting success

Thanks, Kelliandmika. I did what you described and finally got a good update to 10.4.1.10 installed.

I have WinXP 32 bit.

I had been experiencing the same "failure to update" issues for both QT and iTunes described.

Now all is well.

Thanks, I never thought I would be able to find such an easy solution to this problem which has bothered me for nearly two months, I have repeatedly been told that the new version 10.4.1 is available whenever I opened iTunes (and often without opening as well), but I never succeded, it was downloaded but installation failed, also when I tried to install it manually. I phoned Apple for support in Norway, but they were not able to give me any help, just told me a lot of nonsense which did not work. But downloading it directly from Apple/iTunes with uninstalling anything worked beautifully (I have Windows 7-64 bit)

I've been in and (mostly) out of the discussion -- sorry. I've been lurking while traveling overseas.

I followed the Apple support instructions, followed the advice of the thread but still no cigar. Finally, iTunes announced another upgrade, ver.10.5. This works and I can now sync my ipod nano again.

Phew. This was a long period of things not working correctly.

Thanks for the suggestions on this thread.
