If I download the newest version of iTunes to my Mac will I lose everything on iTunes from my version i have now

You should lose nothing.
However, this does not change the fact that you should ALWAYS have a backup copy of everything in your computer, including itunes.
You should ALWAYS make sure that your backup copy of your computer is up to date before any update, restore, etc.

(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 iTunes 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?

HELP! I downloaded the newest version of iTunes and now it won't open.

Hello, Everyone--any help you could give would be greatly appreciated since I am freaking out a bit about this!
I have had iTunes since April when I got my iPod mini. I have downloaded the newer version of iTunes any time it has prompted me to do so when I open iTunes.
So, tonight it tells me there is a newer version. I download it just like always, but this time, when I double click on iTunes, nothing happens. So, I read some of the other posts on here and followed some of the directions like going in to the add/remove hardware and seeing if it's there and then repairing it. I did just that--it's there and it repaired it, but to no avail. I am stressing out now. Now, when I go to shut down my computer, it takes several minutes to shut down--and it never did that before. My computer is newer and was working fine until this happened. Yes, Quicktime appears to be working fine. I am just wondering if I did something wrong or if there is a HUGE flaw with this new iTunes version since it would appear others are also experiencing technical difficulties. Any help any of you could give would be greatly appreciated! I have a Dell Dimension 2400 with the Windows XP operating system. And once again, I have never had problems with iTunes until today. Oh--and when I plug in my iPod, that doesn't pull iTunes up either now. HELP!!!
Thank You,
Alexis

I don't know whom to thank first-- b noir for telling me about the Lorraine fix or Lorraine for figuring out the fix. THE LORRAINE FIX WORKED FOR ME!!! (I feel a little like I am advertising "Hooked on Phonics" with that last line!)
Thank you doesn't say it strongly enough, but THANK YOU b noir and Lorraine for your help. I was to the boiling point last night and starting to get there tonight. Now I am resting easy and thankful that there is a community of computer users out there who care enough to troubleshoot problems together and work together to figure out a solution--and then to take the time to post and share information.
I would STRONGLY suggest that anyone who is having the iTunes issues where iTunes just plain won't open at all after downloading the newest version and has a pc with Norton Internet Security 2005 try the "Lorraine Method."
I am so happy I think I might sing. Or not--I will let my songs on iTunes do the singing for me now that I can again!!!!!!!
And to those still looking for answers--be patient--I now know how incredibly frustrating this can be and I hope that you all find your solutions very very soon!!

My iPhone 4S will not sync to iTunes. I've download the newest version of iTunes several times but when plugging my phone in it says "The iPhone cannot be used because it requires iTunes version 10.6.3 or later."

If you're using Windows try uninstalling iTunes and all of its components as by following this guide exactly: Windows XP or Windows Vista/7, then reinstall the latest version of iTunes. You must follow this guide exactly or it will not be successful. Note: uninstalling iTunes will only remove the application; it will not touch your iTunes library or data.

I am using Windows 7 Home Premium 64-bit OS.I've never had this problem before... today I opened iTunes and it prompted me to download the newest version. I use iTunes all the time and have updated it multiple times with no issues. During the installation process it gave me an error message that said:
Runtime error!
Program C:\Program Files\iTunes.exe
R0634
An application has made an attempt to load the C runtime library incorrectly.
Please contact the application's support team for more information.
I quit the installation, uninstalled iTunes and rebooted my computer. I now receive a similar message with a slight difference:
Runtime error!
Program C:\Program Files (x86)...
R0634
An application has made an attempt to load the C runtime library incorrectly.
Please contact the application's support team for more information.
I did not leave anything out from the error message. It doesn't point to a specific file, it just ends with "(x86)..." Every time I boot up my computer, this error message pops up on my desktop.
How do I repair this issue? I have found multiple suggested solutions but am unsure which one is the best, and I don't want to try a bunch of different things for fear I may make the problem worse. I would like to try and fix this myself if possible but I need to know if that is really possible or if I need to take my computer to someone for repairs. Any suggestions will be greatly appreciated!!

Hi lustyln,
I'm having a little trouble understanding all of what you are trying to explain. From what I can tell, it sounds like your PC has a lot of software problems and you want to know what is supposed to be there and what isn't.
For reference, here are your product specifications:
http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&dlc=en&docname=c01893242&lc=en&product=4043282
To get your PC software back to how it was when it was first purchased, run a system recovery:
http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&dlc=en&docname=c01867418&lc=en&product=4043282
I hope this helps.

HT4527 I transfered my Itunes information using a thumb drive to my new computer and downloaded the newest version of itunes to my new laptop. My songs are all there on the new computer but it won't recognize my ipod and sync.

I transfered my I tunes library to my new laptop using a thumb drive. I downloaded the newest version of Itunes to my new computer. My old ITUNES library of songs and books came across just fine. I can play them on the new laptop but they won't sync with my Ipod. The Itunes shows no devices when I hook it up to the laptop. Windows recognizes that the IPOD is hooked up. But no connection with ITUNES. Did I make a mistake in trying to sync my Itunes purchases to the new laptop before transfering the old library into the new ITUNES. If so how do I undo the problem. Please help. I use a PC with Windows XP.

When I downloaded the newest version of iTunes, my previously downloaded music in iTunes library disappeared on my computer? There was no warning of this happening. What do I do?

Ok, so I downloaded the newest version of iTunes on my home PC, and the previously downloaded music in my iTunes library disappeared on my computer. What happened? I can sync my iPod but I am not sure how long ago I synced it so I may be missing some music downloads. Why did this happen, and more importantly, why didn't iTunes warn me it could happen and advise me to sync with another device before the download? I am not very happy about this and it's a huge issue for iTunes if this is happening. It makes me very wary of iTunes.

Empty/corrupt library after upgrade/crash
Hopefully it's not been too long since you last upgraded iTunes, in fact if you get an empty/incomplete library immediately after upgrading then with the following steps then you shouldn't lose a thing or need to do any further housekeeping. In the Previous iTunes Libraries folder should be a number of dated iTunes Library files. Take the most recent of these and copy it into the iTunes folder. Rename iTunes Library.itl as iTunes Library (Corrupt).itl and then rename the restored file as iTunes Library.itl. Start iTunes. Should all be good, bar any recent additions to or deletions from your library.
See iTunes Folder Watch for a tool to catch up with any changes since the backup file was created.
When you get it all working make a backup!

I just downloaded the newest version of Itunes, I deauthorized all of my computers and now can't find the menu to authorize. It refers to a store menu that doesn't exist on the new software. My account allowed me to deauthorize, but has no option to authorize. I am completely confused with the new software, I just want to download my music to my new computer.

With iTunes 11 on PCs the drop-down menus are hidden by default - control-B should get the menus to show

well i have to be honest, but i don't know if it the vista you use has any significance for this. but you can try.
okay follow:
1: click "start" on the status line on the buttom of your screen.
2: then click on "all Programs" and find "Accessories" and find the "command prompt"
3: Right click with your mouse "command prompt" and click on "run as administrator"
(as you has click'd on "run as administrator", "command prompt" should appear.)
4: when it appears you need to type this "netsh windsock reset"
5: wait for your computer to registrer the command you gave it, and restart your computer.
then erverything should be pretty much as good or better then new.

OK. You may have to reinstall everything from scratch but follow following steps:
1. Go to Microsoft website to fix install and Unistall problems. Click "Run now" from Fix it to remove all iTunes & related installer files:

Just downloaded the newest version of Itunes. Now my Iphone 4s won't sync with Calendar in XP Outlook. Has anyone else had this problem, and how did you fix it? I've already made sure the proper check boxes are on in Itunes and tried the reset sync history. Also re-downloaded Itunes again. Same problem.

Well, OSX 10.9.2 is free, which should solve the iTunes problem, but 10.9.2 isn't bug free, & you'll lose the ability to run any PPC Apps if that important, as well as needing to update many Apps & Printer Drivers.
