Cannot load Itunes or Quicktime and can't uninstall old version

I'm trying to load iTunes. The installation fails because, "The installation of QuickTime did not complete successfully. iTunes requires QuickTime."
Have tried unintallation the current version of QuickTime and installing the latest version of QuickTime 7. Nothing works.
What should I try next?

This topic has been discussed repeatedly, if you go up to the top right corner of this page to "more options" and do a search of the forum you will likely find your answer, it does take a little effort on your part though.
This is a series of post from about a week ago.

Cannot use Itunes or Quicktime, nor can I uninstall them!....

The software worked fine until one day, maybe a month ago, that I was getting the "unexpected error" window everytime I open either programs. I get the window usually 3 seconds after opening the file, and nothing shows up but the error window. I try uninstalling and I receieve a "a fatal error has occured" window, and the uninstall stops.
I have NO clue how to go about troubleshooting this. I've done all there is with my knowledge and all that the support page has had to offer.
If anything has any input on this, that would be great!
Thanks!

Hi,
I had exactly the same problem you're describing, and I finally managed to resolve it yesterday. Here's what I did (with the caveat that although it did work for me, any manual deleting and registry editing is done at your own risk!):
*Uninstalled iTunes, and Apple Software Update from the Control Panel. Restarted the system.
*A complete manual uninstall of QuickTime, following the excellent advice given here: http://pabsungenis.livejournal.com/94683.html. The only thing I didn't do was install QuickTime at the end, as he recommends.
*Searched all hard drives for QuickTime folders and files, and deleted these. I found that in addition to the dll files in "Windows/System32", there was a QuickTime folder in System32 as well, which I deleted. In those cases when it seemed that a QT file was used by another 3rd party program as a plug-in, I just renamed or moved the file.
*I also manually removed all Apple folders under "Documents and Settings/<username>/Application Data" and "Documents and Settings/<username>Local Settings/Application Data" for every user on the system. Deleted the iPod, iTunes and QuickTime folders in Program Files as well.
*Emptied the Recycle Bin and restarted the system.
*Installed an older version of iTunes (7.4), which I found on www.oldapps.com.
*Restarted the system after installation had finished.
To my great relief, and surprise, this worked - I've now got iTunes up and running again! I haven't yet updated to a newer version, as this one seems to work well with my old 40GB iPod without video and my wife's 80GB iPod Classic.
Hope this helps,

ITunes-Won't upgrade, can't removed old version, can't add new version,etc

I just bought a new Ipod yesterday, 30GB Photo/Video. I connected my Ipod however it was not responding to the old version of iTunes which I had, this is when the problems started.
1st. I tried to update my iTunes, I tried with the new disc which came with my Ipod and also from the internet. I tried running and saving the program - both times I received a Error Msg as following:
Error 1406. Followed by some numbers and letters as well as: Verify that you have sufficient access to that key, or contact your support personnel.
2nd. I tried to remove my old version of my iTunes to see if I could then use the CD to add the new version, however when I tried to do so I got this Error Msg:
Error 1402. Could not open key: followed once again by some numbers and letters as well as: Verify that you have sufficient access to that key, or contact your support personnel.
Followed by Error: -1603 Fatal error during installation
Consult Windows Installer Help (Msi.chm) or MSDN for more information.
Seems like I've tried everything to install, update, and even delete my old version of iTunes to try and get the new version, nothing seems to help. I never had this problem before with my old Ipod, but I'm ready to switch over to my new one. SOME ONE PLEASE HELP!!!!!
Thank you

I tried following the steps in the Troubleshooting, however I cannot complete them all as I cannot remove the older version of my iTunes from my computer.
I've emptied my Temp directory and restarted with the same result.
One thing I noticed is I cannot seem to find my Windows installer anywhere on my computer. Could this be a problem?
I've turned off my fire wall, turned off my anti virus program, and updated my computer all with the latest updates.
I've tried placing the program in different locations to see if this would work, but no such luck.
This is what I receive when I try to add the new iTunes from the CD:

My computer crashed and I got a new one and down loaded itunes and I can not fined my account

If you mean your content then have you copied it onto your new computer from your backup and added it to its iTunes via File > Add To Library ? If you haven't got a backup then if you have any of your purchases on your iPod then you should be able to copy them to your new computer's iTunes via File > Transfer Purchases, or you might be able to re-download some/all of your previous purchases (what content types you can re-download depend upon which country that you are in and whether it's still in the store) : re-downloading.

Error 42408 with iTunes 10.3 and can't Uninstall?

I can't buy music, play purchased downloads or authorise my computer. I have tried all of the methods posted here, such ejecting and reconnecting iPod, replacing the shortcut, rebooting my laptop, closing and reopening itunes, logging in and out again of my itunes account, removing SC info folder and the .plist files/version without extension and I am at my wits end with this.
The only thing I haven't tried is reinstalling because I can't uninstall iTunes and the change/repair options in add/remove hardware don't work either. I left it for hours trying to uninstall and it stuck on "preparing to remove."
I have Windows Vista 32 bit and am in the administrators account, if that is any help.

pfhannan:
Thought i had too much stuff in it,
On the contrary, the stuff that is on it gives the history of the issues with which you are dealing, and makes it easy for responders to make suggestions. Be sure you provide information requested by responders, so that their suggestions will be pertinent. I will take a look at the thread again and see if I have any suggestions to offer.
Good luck.

Can't uninstall old version of iTunes on Windows Vista

I have been trying to install updates for iTunes for a long time now (pretty much since update 7) and have not been able to do so because once the install occurs I'm that there is a resource network unavailable. I'm them prompted to change the file path to something that contains "iTunes.msi". I do that and it doesn't work. When I search my computer for the "iTunes.msi" file it can't find it but during the download process the option is given to me when I browse, but it still doesn't work.
I have tried a manual download of iTunes. I have tried to uninstall iTunes from my Control Panel and get the same response as above.
This issue is only affecting iTunes. Other Apple programs have been able to update.
Help.
Thanks.

Try using Microsoft's Fix it solution at http://support.microsoft.com/mats/Program_Install_and_Uninstall. Use it to uninstall iTunes. It bypasses this not uncommon problem. When the solution finishes, the selected program will be uninstalled. It can take several minutes and I have seen as much as half an hour.
After it uninstalls iTunes you should be able to install the new version.

Installed skype 7.6 but can't uninstall old version.

Hello, I recently upgraded to 7.6 as advised and it works fine. However, the old version is still installed and continues to ring and ring when I connect on the new version.I cannot find the old version on my programmes list to uninstall it. What has happened here?

downloaded quicktime standalone version, no luck there, says it can't uninstall the old version, error 1714, then it says fatal error -1603 during installation.
let's first try this technique to see if we can get past the 1714.
Download and install the Windows Installer CleanUp utility. then use it to clear any existing QuickTime installation configuration information from your PC:
Description of the Windows Installer CleanUp Utility
next use the QuickTime component of the complete uninstall instructions in the following document as a guide to a manual removal of leftover QuickTime program files and folders.
Trouble installing iPod, iTunes, or QuickTime software in Windows
once we've got all the existing QuickTime scraped away, let's try another careful standalone QT 7.1 reinstall.
download and save a copy of the QT 7.1 standalone installer to your hard drive. (we'll run the install from there rather than online.) switch off antivirus and antispyware applications prior to the install.
Quicktime 7.1 Standalone Installer
if that install goes through okay, does your itunes launch properly again?

HT1923 Can not uninstall old version because the file it is looking for is not found on windows 8.1

First off I want to start that I am an IT professional, so not a dumb PC user.
I am running Windows 8.1. I have been running Itunes for a long time and when the auto-updater prompted me for an update, I used that to update. Aparently something happened during one of the updates and Windows thinks I have v 11.1.1.1 installed as well as the newest version. I discovered this when I connected my Ipod recently (It was a few months since my last sync) and it wasn't be recognized by Itunes. Windows discovered it as a device but Itunes wouldn't see it. I went to the forums/support and tried the trouble shooting steps to no avail. I finally did the normal "uninstall/reinstall" process and that is when I saw the two entries in the programs list in windows. I uninstalled the current version. When I tried to reinstall it would error out with "can not find the path to iTunes64.msi". I had a few of them in the path but they were for newer versions, not the 11.1.1.1. Then I looked around and saw the directory tree for Itunes were still there.
I tried to edit the registry in the local machine->uninstall hive but itunes was not on the list there because I went through every entry. They all had the names from programs on the list but Itunes wasn't there. I uninstalled everything else as per the Itunes support instructions (Quicktime/Bonquor/Etc) and still it didn't work. I deleted the Itunes directory manually and then ran CC cleaner to a few times to clean out all the broken registry entries. After that was done I still couldn't install Itunes because it detected the program from the list in windows that said it was installed (v 11.1.1.1). I restored the directory from my recycle bin, launched the exe directly and it worked and I was able to detect/sync my Ipod. BUT the system doesn't think I have it installed so I have to manually kick it off from the exe itself.
I want to fix this. I would think it would be to edit something, registry I assume, that populates that installed program list and then the newest installer should run fine. I am stuck so I am looking for help. Any suggestions/ideas or anything?
Thank you in advance.

I can't seem to find a way to delete this...SO I unmarked it as a question.
I solved the problem, I aparently missed the program ID number when I searched. I found it and then went through the registry and removed the other references to that ID. Once I did that I was able to install the new Itunes without incident. In the process it also cleaned up the old entry on my programs/features list.
Even though I checked the registery 2x trying to clean up references to Itunes, the search and my manual look through the Uninstall entries I missed it. Sorry to waste anyone's time.

Itunes can't play recent TV Show (downloaded via itunes) without Quicktime and can't sink same show to IPod??

Problem 1:
I recently bought the HD Season Pass to Please Like Me's second season, and when I went to go watch the first (and as of this writing the only) episode, Itunes kindly informed that I needed QuickTime to watch it. Installing Quicktime has not solved this.
The QuickTime pop-up also came with a 'more info' button which according to that link, QuickTime is needed for older media (which considering this season is of the more recent variety (aka THIS MONTH) I would consider this to not be 'older'). Itunes otherwise more or less outright says that media of any variety should be able to be played just by Itunes, especially if you literally just bought it off the Itunes store.
Itunes is updated to the most recent version. I'm running on Windows 8.
Problem 2:
With the same aforementioned media, when I tried to sync it to my Ipod Touch (5th Gen, up to date), I was greeted with the lovely little message that more or less said that 'x was not synced because x cannot be played on this Ipod'. Following this I went to the iTunes store on my Ipod and downloaded it from there and lo and behold, it has downloaded with no problems.
So why is it that I had to go the more roundabout way and time consuming way to transfer the episode?

Hello bianca729
I would check to make sure you can download the show again. If you can, then delete the show and download the TV show again. If it still not working, then report the issue with the download with the other article below.

What happens if I don't update iTunes when prompted and stay with an old version?

I ask because I hear about so many problems people have when they do apply updates.
Basically, what am I missing if I don't?

The new features included with the updates, which include the ability to sync recent devices.
