Tried updating iTunes- error 7 (Windows Error 127)

I tried to update my iTunes on my Windows XP and the download went fine but now when I try to open it I get an error 7 message along with (windows error 127) what do I do now?

Brilliant. Thanks a lot. I've wasted a couple of hours on this nasty bug, & trying all the other suggestions across various threads again and again.
I now find I had the same registry entry hanging on, despite uninstalling & wiping everything again and again. Having now deleted this key, (I don't even have an iPod), & iTunes 11.1.14 now opens at long last.
But WHY is this bug not fixed? Enough people are suffering with this across the forum. WHERE is Apple support on this?
It should have been added to their page at
http://support.apple.com/kb/HT1923
by now, why hasn't it???
It's not good enough!
Re:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\SharedDlls]
"C:\\Program Files\\iPod\\bin\\iPodService.exe"=dword:80000000
AHA! This entry for iPodService.exe still exhisted. So I had no folders on the PC, no installs on the PC and no services running.... BUT this was still in the Registry.
Step 5 - Delete only the Registry entry above. NO REBOOT
Step 6 - Reinstall iTunes64.exe

Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.

TS1717 I tried updating iTunes and now I get an error. I followed instructions to uninstall and then reinstalled but the error I get Is "Error 7 (Windows error 193)" - anyone help?

Error 7 (Windows error 193) was received when I just tried to update iTunes on my Windows 7 computer. I've uninstalled and tried twice to reinstall and I get the same message. Does anyone have any additional suggestions? During install I do get a message about the mobile device but I do not have iTunes on my mobile phone.

Go to Control Panel > Add or Remove Programs (Win XP) or Programs and Features (later)
Remove all of these items in the following order:
iTunes
Apple Software Update
Apple Mobile Device Support (if this won't uninstall move on to the next item)
Bonjour
Apple Application Support
Reboot, download iTunes, then reinstall, either using an account with administrative rights, or right-clicking the downloaded installer and selecting Run as Administrator.
The uninstall and reinstall process will preserve your iTunes library and settings, but ideally you would back up the library and your other important personal documents and data on a regular basis. See this user tip for a suggested technique.
Please note:
Some users may need to follow all the steps in whichever of the following support documents applies to their system. These include some additional manual file and folder deletions not mentioned above.

Hi hongkongpom,
Just wanted to say that after posting the problem, I had a chat with an iTunes' Tech Support, her name is Rebekah. My problem was resolved after that. Will list the chat history below in hopes that it may help you as well.
Good luck!
Samia
Chat Transcript
Friday, October 4, 2013 05:55 AM
Duration: 81 minutes 28 seconds
Rebekah:
Welcome to AppleCare chat support. Please give me a moment to look over your information.
Rebekah:
Hi, Samia! My name is Rebekah. If we get disconnected, please chat us back. http://www.apple.com/support/ipod/contactEnter the case number from the initial email we sent you. This gives the next advisor you chat with immediate access to your case history.
Rebekah:
Could you please confirm your serial number? I want to be sure we provide the best service possible for you, Samia!
SAMIA:
Sure, it's 8L8395UY2C5
SAMIA:
My problem is with iTunes.
Rebekah:
Thanks for that confirmation. Just a heads up, this is iOS Tech Support. We do support iPod touches, iPads, and iPhones, but not the iPod classic. But no worries! I can get you in touch with a phone Advisor who can get you in touch with the department that specializes in iPod classics and would be able to better assist you. Would that be OK?
SAMIA:
I wasn't able to install the new version of iTunes (version 11.1.1). The installation keeps failing. The they suggested the I install it manually and that failed too. I will attach the message I received.
SAMIA:
I don't have a problem with iPod.
SAMIA:
Just iTunes
Rebekah:
No problem! We can certainly troubleshoot iTunes as much as possible. It may come to the point that you may have to transferred, but we can do as much as possible during this chat!
Rebekah:
Thanks for the screenshot. It is a bit small so I am unable to fully see the message that you are receiving. What is the error message you are receiving?
SAMIA:
This is the message I received in case you weren't able to open the attachment: "The installer has encountered an unexpected error installing this package. This may indicate a problem with this package. The error code is 2324."
Rebekah:
Thanks for that info!
SAMIA:
Pleasure!
Rebekah:
What version of Windows (XP, Vista, 7) do you have?
SAMIA:
Windows 7
SAMIA:
Windows 7 Home Premium
Rebekah:
Thanks for that confirmation. I do apologize for the delay, Samia. I am researching this error code now. You mentioned trying to install iTunes manually. To be sure I am on the same page, what steps did you take to do that?
SAMIA:
Well when the indsatalltion failed I was given instructions to select Download Only from Tools and then install manually. When I did it, I window popped up with the following items: - AppleApplicationSupport
SAMIA:
- AppleMobileDeviceSupport64
SAMIA:
- Bonjour64
SAMIA:
iTunes64
SAMIA:
SetupAdmin
SAMIA:
I selected Repair in all of them instead of Remove and all worked but iTunes64
SAMIA:
That's when I received the message that I sent you earlier.
SAMIA:
By the way, this is the fir st time something like this occured. I never had problems with installation before.
Rebekah:
I completely understand what you're saying. Since that Repair did not resolve the issue, our best option is to uninstall iTunes and its components and redownload it. To do this, we will follow the steps in this article: Removing and reinstalling iTunes and other software components for Windows Vista, Windows 7, or Windows 8
Rebekah:
First, we will want to quit iTunes and/or Apple Software Update if those are open at this time.
SAMIA:
Rebekah, the instructions you gave says, "For Windows XP, follow these steps to remove and reinstall iTunes and other software components for Windows XP."
SAMIA:
I closed all applications
SAMIA:
Also, my iTunes doesn't open anymore after the new failed installation.
Rebekah:
The section that says "For Windows XP…" is in case we opened up the wrong article, as we have the one for Windows Vista, 7, or 8. There is a link to click ("these steps") in those directions that would take us to the article for uninstalling on a Windows XP.
Rebekah:
So no worries! We have the right article!
Rebekah:
On the computer, we will want to click on Start > Control Panel. In Control Panel, we will click the "Uninstall a program" link.
SAMIA:
I thought so after doing a little exploration.
SAMIA:
done
Rebekah:
Alright, we'll want to select iTunes from the list of currently installed programs. Then we will click Uninstall. When asked if you would like to remove iTunes, let's click Yes.
Rebekah:
After the uninstallation is complete, we don't want to restart your computer if you're prompted.
SAMIA:
Done
Rebekah:
Then if you see other iTunes entries on the list, we'll want to remove them the same way.
Rebekah:
Then we will remove all instances of Apple Software Update the same way you removed iTunes.
SAMIA:
Okay, but do I have to remoce iCloud as well?
SAMIA:
Rebekah, I received the same error message again when uninstalling
Rebekah:
We actually do not need to remove iCloud. After the Apple Software Update, we will want to remove all instances of Apple Mobile Device Support
Rebekah:
How strange! Are you able to click past that and allow the process to continue or has it stopped it completely?
SAMIA:
I am unable to uninstall iTunes either
SAMIA:
Stopped completely
SAMIA:
I treied clicking Repair
Rebekah:
Alright, after trying the Repair option, let's see if it will allow us to continue uninstalling or not.
SAMIA:
I tried that but unfortunately, it isn't working. I still get that same message with error code 2324.
Rebekah:
This error code is not something that I am finding in my sources, Samia. So there is a chance that it is being caused with the Windows computer itself. However, I did find a link that may be able to help with uninstalling iTunes from Windows' support site: http://support.microsoft.com/mats/Program_Install_and_Uninstall
SAMIA:
Rebekah, you're a genius! It worked! iTunes is no longer there. What next?
Rebekah:
Awesome! I'm glad that worked!
Rebekah:
To be sure I am on the same page, what was the last component we uninstalled?
SAMIA:
iTunes
SAMIA:
Shall I remove the Apple Application Support, Apple Mobile Device Support, and Apple Software Update
Rebekah:
That is correct! However, we do want to uninstall it in the order I mentioned above. So Apple Software Update first, Apple Mobile Device Support next, and then Apple Mobile Device Support.
SAMIA:
Got it, but is the second one to uninstall Apple Mobile Device Support OR Apple pplication Support?
Rebekah:
The second one is Apple Mobile Device Support.
Rebekah:
The Application Support will be the last component we uninstall.
SAMIA:
Thanks! I'm on it.
SAMIA:
Done! ll 3 are gone, well 4 with iTunes. Now what?
Rebekah:
Awesome! Also, I just noticed that I accidentally typed Apple Mobile Device Support twice, I do apologize for any confusion! Now we will remove all instances of Bonjour and then remove all instances of Apple Application Support.
SAMIA:
There was only 1 instance with Bonjour. I don't know what the instances are for Apple Application Support
Rebekah:
Yes, Bonjour is often only listed once. Is the Apple Application Support listed at all?
SAMIA:
No
SAMIA:
Since I removed it
Rebekah:
Oh, perfect! If it was removed, we should be set!
Rebekah:
We have removed iTunes and its components now! From here, our next step is to restart the computer. Then once you reboot, you can redownload iTunes from apple.com/itunes
Rebekah:
That should allow you to download iTunes!
SAMIA:
Shall I downloaad the latest vesion?
Rebekah:
You will want to first restart the computer as shown in the article. That will ensure that this process goes smoothly and that everything was removed correctly! Then you can try downloading iTunes again.
SAMIA:
Okay, thanks Rebekah!
Rebekah:
You're very welcome! I'm glad I could help! And of course if you have any issue after the reboot and download, you can always chat us back, as chat is open 24 hours! You will just need to give your case number and the next Advisor would have all my notes!
SAMIA:
Thanks again for all your help, for I couldn't have managed with out it. Have a nice day!
Rebekah:
You're very welcome! I know how important iTunes is and I'm glad we could get you on a path to resolution!
Rebekah:
I hope you have a lovely day!
Rebekah:
It's been a pleasure speaking with you! Thanks for chatting with us Samia. If you don't have any more questions, select End Chat from the upper left corner of the chat window.
SAMIA:
Will do, thanks.

I just tried updating ITunes to the new version and it will not completely download and now I get an error message of MSVCR80. Is there a problem with the new iTunes version?
Now ITunes won't open.Help!!!

Go to Control Panel > Add or Remove Programs (Win XP) or Programs and Features(Later)
Remove all of these items in the following order:
iTunes
Apple Software Update
Apple Mobile Device Support
Bonjour

Reboot, download iTunes, then reinstall, either using an account with administrative rights, or right-clicking the downloaded installer and selecting Run as Administrator.

Should you get the error iTunes.exe - Entry Point Not Found after the above reinstall then copy QTMovieWin.dll from:
C:\Program Files (x86)\Common Files\Apple\Apple Application Support
and paste into:
C:\Program Files (x86)\iTunes
The above paths would be for a 64-bit machine. Hopefully the same fix with the " (x86)" omitted would work on 32-bit systems with the same error.

When updating iTunes on my Windows PC, I am getting a M/S Visual C runtime error...can anyone suggest how to fix it?

When updating iTunes on my Windows PC, I am getting a M/S Visual C runtime error...can anyone suggest how to fix it?

It has been discussed a few times, and is even available in the Apple support web site. Basically, you need to un-install all teh Apple software you have installed, then re-install it all. When you re-install, right click on theinstaller and select "Run as Administrator" to make sure it has The proper rights to complete the installation.

(1) Download the Windows Installer CleanUp utility installer file (msicuu2.exe) from the following Major Geeks page (use one of the links under the "DOWNLOAD LOCATIONS" thingy on the Major Geeks page):
http://majorgeeks.com/download.php?det=4459
(2) Doubleclick the msicuu2.exe file and follow the prompts to install the Windows Installer CleanUp utility. (If you're on a Windows Vista or Windows 7 system and you get a Code 800A0046 error message when doubleclicking the msicuu2.exe file, try instead right-clicking on the msicuu2.exe file and selecting "Run as administrator".)
(3) In your Start menu click All Programs and then click Windows Install Clean Up. The Windows Installer CleanUp utility window appears, listing software that is currently installed on your computer.
(4) In the list of programs that appears in CleanUp, select any Bonjour entries and click "Remove", as per the following screenshot:
(5) Quit out of CleanUp, restart the PC and try another iTunes install. Does it go through properly this time?

Why am I having trouble updating itunes on my windows 7 (64 bit) computer?

Doug
Thanks for the update.
nothing is getting installed, copied or otherwise loaded onto my computer....first the program starts to load, then it asks for my serial number, then it goes out and seems to check the serial number then it says it can't be installed then it erases everything it just spent 10 minutes loading.
In view of the above and your prior descriptions, have you tried alternative installation files?
If you want to give a look to that approach, please download and install the tryout files for Premiere Elements 9 from the following web site and then insert your purchased serial number into them during installation.
With this route, you need to carefully carry out the web site's "Note: Very Important Instructions" in order to avoid an Access Denied message.

Back to my questions from post 3
Are you getting any Shared Technologies error message any where in the installation process that is failing?
If you follow the following path, do you find an OOBE Folder?
Local Disk C
Program Files (x86)
Common Files Folder
Adobe
and in the Adobe Folder should be the OOBE Folder which you rename from OOBE to OLDOOBE to disable it.
When you are forced into a roll back for whatever installation has taken place, do you ever see a message about Shared Technologies?
And, whether or not the program installs to any extent, does your computer have the OOBE Folder? If so, then please rename it to disable it before
you try for another 9 install.
Looking forward to your results.
ATR
Add On....Please remind me....since you purchased Premiere Elements 9, have you ever installed and used it successfully on any computer?
