Can't upgrade or uninstall iTunes due to: The folder My Music contains an invalid character!

Hi,
Something went wrong when i tried to upgrade to 10.5 and now I can't use iTunes. It says that the folder My Music contains an invalid character and although I've tried uninstalling all apple software and re-installing I can't uninstall/repair or upgrade iTunes. It's driving me mad! Help pls someone - i can't even find the fault listed anywhere else - is it just me ??
Regards....Chris

'The folder path "C:" contains an invalid character.' ERROR AS I INSTALL iTunes

hi
first of all, merry xmas to all that celebrate! i hope you had/have a memorable day!
and wishing everyone the very best for the new year.
Now, I have a problem when I try to install iTunes on my computer. I'm running:
- Windows Vista (Home Basic)
- iTunes 10.5.2.11
i have sufficient hard-drive space and sufficient ram. its definetly NOT from that. I originially DID HAVE iTunes already installed on my computer, but I was frequently having problems with establishing a connection through my iPhone 4. So I thought it would be a good idea to delete it and try downloading a new version, then install it fresh!
I have some computer skills and knowledge, and i know how "most" things work and run. But now I am totally stuck. I run the iTunes software to be installed, but the installer keeps giving me an error message and NOT installing. I've done all the easy and required steps after I deleted the original version of iTunes from my computer, and now I need help from someone who really knows their stuff in IT and computer software. I have a feeling it may be a string of codes that are corrupt or significantly different to what they should be, but thats just my guess! cos like i already said, ive tried all the common fixes already but have been unsuccessful thus far. Some of the things I did were:
- Restart the computer, re-boot, login to Windows, run the iTunes installation
- Turn off the computer, wait 10 minutes, re-boot and then run the iTunes installation
- Delete ALL the "Apple" company software that was still installed on my computer (QuickTime, iPhone Utility, iPod, Bonjour, etc etc)
- Confirm my "User Account Control" is OFF
- Run the iTunes installation file from my secondary windows login account (which has "Administrator" privilages)
- Create a new windows login account, turn off the UAC (User Account Control protection), then try installing iTunes
- Run disk-error checks on my hard-drives incase there are missing/corrupt/misplaced files that needed repair
etc etc etc etc
Nothing worked! THIS BELOW IS EXACTLY THE PROBLEM I KEEP GETTING WHEN I DOUBLE-CLICK ON THE iTUNES INSTALLER:
- Double click on the iTunes install icon
- The "Trusted File Security Warning/Confirmation" window appears, requesting I confirm to Run or Cancel the software installation. I click on "Run"
- A horizontal grey bar appears in the middle of the screen, and quickly fills up green
- Then a small installation windows appears (Windows Installer) that writes "Preparing to Install". Then it very fast writes a couple different sentences (which is normal), specifically the sentences are "Performing installation checks" and "Checking spacing requirements".
- immedietly after the previous step, another window appears and I hear the "error" audio tone. The ERROR MESSAGE has the Yellow Triangle logo with an exclamation mark in the middle, and beside it displays the following text (and Ive attatched the screen shot too):
THE FOLDER PATH "C:" CONTAINS AN INVALID CHARACTER
then below this message theres the "OK" button which I have no choice but to click on. then the next window that appears is as follows (see screenshot), and it reads:
iTunes Installer Completed
The installer encountered errors before iTunes could be configured.
Errors occured during installation. Your system has not been modified.
Please run the installer again, or click Finish to exit
Please I beg you guys to help me, I will be extremely grateful for ALL and ANY advice/tips/assistance/solutions I receive. And would owe you one for sure!!
Please feel free to write your opinions and thoughts on what I could do different, as Ive used up all my knowledge regarding the matter, and have seriously hit a brick wall now.
Thanks so so so much, and once again I wish everyone the absolute very best!
regards.
PS. Replies can be posted in this thread, otherwise even sent to me via email if you wish to do otherwise. My email address is: [email protected]

Resolution:
Check for the existence of a hidden folder named %appdata% in the C:\Program Files\Microsoft Application Virtualization\Client folder. (You will need to un-check the folder options box in windows explorer for "Hide
protected operating system files" to see it)
If the hidden %appdata% folder exists, delete it.
Proceed to uninstall the App-V client
After a clean uninstall and removal of remnants of the client, reinstall the client again and apply the latest hotfix available (Hotfix 2 for SP2 at a minimum).

Error when uninstalling App-V RDS client: Product: Microsoft Application Virtualization (App-V) Client for Remote Desktop Services 5.0 Service Pack 2 x64 -- Error 1324. The folder path 'C:' contains an invalid character

Issue: experienced when attempting to uninstall the App-V 5.0 SP2 RDS client.
Event Log: Product: Microsoft Application Virtualization (App-V) Client for Remote Desktop Services 5.0 Service Pack 2 x64 -- Error 1324. The folder
path 'C:' contains an invalid character
Symptoms (when in this current state):
Unable to uninstall the SP2 client
You can upgrade the client (via hotfix) and uninstall the hotfix, but you will not be able to remove the SP2 client
AppvVfs filter driver will not create an instance, therefore applications will not be able to read into existing streamed VFS content, or trigger sparse files to stream content. (you can still stream the content via other means, like the UI or powershell)
Because of the AppvVfs filter driver not instantiating, applications that depend on licences that exist in VFS will not be able to be read causing certain applications to react as if the license does not exist or is an incorrect format

Resolution:
Check for the existence of a hidden folder named %appdata% in the C:\Program Files\Microsoft Application Virtualization\Client folder. (You will need to un-check the folder options box in windows explorer for "Hide

ITunes 7 upgrade fails: The folder path 'C:' contains an invalid character

I see this message when I try to upgrade to ITunes 7.
The path selected is C:\\Program Files\iTunes (the default one).
Also tried to manually browse to this directory, in case something was wrong with default path.
Also tried running Registry Mechanic in case there were strange characters in any of my registry settings.
Nothing helps.

I am trying to update iTunes and keep receiving the message "The folder path "My Music" contains an invalid character

I am trying to update iTunes and keep receiving the message "The folder path "My Music" contains an invalid character.
The folder where everything is stored isnt even called My Music, it is just called Music.
I gave up on trying to update my itunes and removed it and am trying to re-download but receive the same message. Now I have no itunes on my computer at all.
Short or wiping my computer and starting again I have no ideas left.
Please help!

That message isn't referring to the location of the music, it's referring to the location of the iTunes programme.
So the message is either referring to the download location or the folder it is trying to install the programme in. I think (I wouldn't put money on this) that invalid characters will be things such as * ^ % and so on. When you get the message, look for the location that your computer is trying to use. Are there any strange characters in the "file path" that your computer is using?

Can't upgrade or uninstall itunes

I have tried to upgrade itunes but I get a message saying it cannot find itunes.msi. The forums say to uninstall itunes and reinstall it but when I try I get the same message that it cannot find itunes.msi. What am I supposed to do if the file that both procedures need is not found?

The folder path 'Itunes Music' contains an invalid character

Please help? I just got a new computer and dowloaded itunes off of the apple site.

It usually indicates that there's damage to the iTunes installation database in your iTunes.msi file for your current version of iTunes.
Unfortunately, these sorts of msi-related troubles have gotten more complicated to deal with ever since Microsoft pulled the Windows Installer CleanUp utility from their Download Center on June 25. First we have to find a copy of the utility.
Let's try Googling. (Best not to use Bing, I think.) Look for a working download site for at least version 3.0 of the Windows Installer CleanUp utility. After downloading the utility installer file (msicuu2.exe), scan the file for malware, just in case. (I use the free version of Malwarebytes AntiMalware to do single-file scans for that.)
If the file is clean, to install the utility, doubleclick the msicuu2.exe file you've downloaded.
Now run the utility ("Start > All Programs > Windows Install Clean Up"). In the list of programs that appears in CleanUp, select any iTunes entries and click "Remove".
Quit out of CleanUp, restart the PC and try reinstalling iTunes again. Does the install go through properly this time? If so, are you able to launch iTunes without the error message?
(If you do find a clean download site for the correct version of CleanUp, please don't tell me where it is. Without wishing to sound paranoid (although I grant it does sound paranoid), there is a non-zero chance that posting links to download locations for the utility here at Discussions leads to that download location being shut down.)

I can't install or uninstall itunes. Says the iTunes.msi file is not a valid file. My iTunes started acting odd after having the Windows XP virus. I got ride of the virus, but then the repercussion of having it have wrecked havoc.

An error pops up saying that the file isn't found and then when I link it to the file, the error says it isn't a valid itunes.msi file. I had iTunes on my PC but it won't work properly so I am trying to re-install or update it. Neither works.

So I tried installing it and when I did it stopped at a certain point, giving me a message about "not being able to write to the file C:\ProgramFiles\iTunes\ iTunes.Resources\fr.lproj\ipodsettings.nib\objects.xib"
problems with language resource files and folders (i believe that's one of the French ones that you're having a problem with) are often produced by disk damage around the areas of the files in question.
so perhaps let's try running a chkdsk over your C drive. see:
How to perform disk error checking in Windows XP
does the chkdsk find/repair any damage? if so, does the uninstall or reinstall go through any better afterwards?

Hey bcolden,
I would try uninstalling and reinstalling following the directions in here:
Removing and reinstalling iTunes and other software components for Windows Vista, Windows 7, or Windows 8
http://support.apple.com/kb/HT1923
This section in particular contains important information in the uninstall process:
Use the Control Panel to uninstall iTunes and related software components in the following order and then restart your computer:
iTunes
Apple Software Update
Apple Mobile Device Support
Bonjour
Apple Application Support (iTunes 9 or later)
Important: Uninstalling these components in a different order, or only uninstalling some of these components may have unintended affects.
Let us know if following that article and uninstalling those components in that order helped the situation.
Welcome to Apple Support Communities!
Best,
Delgadoh

When I try to back up my Iphone, I get a message that My Iphone can not be backed up on my computer. My computer is authorized and I have been successful with this in the past. I uninstalled Itunes and reinstalled the lastest version and the same problem occurs.

If you are running Tiger, you don't have time machine.
You need to get something like SuperDuper! or Carbon Copy Cloner (sorry, I don't have a handy link for CCC but you can Google it to get their site) to make a clone of your drive on the external and then do incremental backups. The free versions do a lot and you can upgrade to the full-service versions for small change if you need more. The one time I used SuperDuper! for cloning a volume it worked just fine.
(My backup application is the last PPC capable version of Retrospect, which does a credible job, or has over the past ten-twelve years.)

I can't install on uninstall iTunes on my laptop; running Windows XP. I've tried all the steps in Apple Support as well as Windows support. Can anyone help? I fet the error "The feature you are trying to use is on a network resource that is unavailable

I can't install or uninstall iTunes on my laptop. I've followed all the steps on Apple Support as well as Microsoft support. I get the error "The feature you are trying to use is on a network resource that is unavailable. Pick an alternate path to a folder containing the installation package 'iTunes.msi". This has been going on for a couple of weeks now and I'm very frustrated. From what I can see, I'm not the only one with this problem, but I have yet to see anyone post a solution that works. Microsoft wants to charge me $99 to troubleshoot it for me and Apple will charge $20. I think both are ridiculous as this is obviously not "operator error".

(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?
