I can't deinstall iTunes due to error 0x80070091.

I can no longer access iTunes from Windows 7. Following the support protocol I am deleting all Apple related software,but cannot delete the iTunes folder. It says the folder is empty but when i try to delete, it reports an unexpected error is preventing you from deleting..." I can't open the folder as it says file is corrupt or unreadable.

More info would be helpful - which Mac, which OSX are you using, version of iTunes etc. New download of what?

I can't open Itunes due to error -45075. What do I do?

I can't open Itunes due to error -45075. What do I do?

I Had this problem along with the error message that it's missing the driver GNSDK_DSP.DLL. I am Windows XP and fixed the error by going to Start>My Computer>Add or Remove Programs
When the Add or Remove programs list is "populated", Find iTunes on it. Click the link that says "For more information" and the iTunes box will expand. You will see a button that says "Repair" and it says to reinstall the program if it is not working correctly, use the "Repair" button. I clicked the Repair button and it automatically started the reinstall. When all the progress bars disappear (it doesn't really give you any other indication that its done) click the "close" button and try to open iTunes again. It worked first time for me. I also saw another forum where someone said it worked for the other Windows versions by following the same route, just that in other windows versions it might be "Computer" instead of "My Computer" and the Add or Remove Programs function is also called something else. Hope this helps somebody having this problem. It drove me crazy finding the answer, but the fix was super simple once I found out what to do.

That suggests that the installer is getting damaged during the download.
I'd first try downloading an installer from the Apple website using a different web browser:
http://www.apple.com/itunes/download/
If you use Firefox instead of IE for the download (or vice versa), do you get a working installer?

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

I pulled my brains out trying to figure this bug out and I may have a solution for you.
All of it installed fine in my desktop, but a friend's laptop got the error you mentioned on quicktime, itunes, flash, officeXP and about anything else I tried to load for him.
If you look in: C:\documents and settings\<username>\Local Settings\Temp there will be an iTunes install log...open it in Notepad and see if it isn't exiting with a 1619 error while running msiexec.exe
If this is the case, this fix should work for you.
Seems some configurations of XP (and possibly Vista) aren't allowing full administrator rights to the account you set up when you installed XP (even though User Editor says you do have those rights.)
I read 2 MS articles and turned off simple file sharing, then gave ownership of the entire C: drive to the administrator. Logged the admin account off, logged his "admin" account in, and then gave rights to his personal directory to his account (c:\docs and settings\<username>)
Once I did that, every install that had previously errored out performed flawlessly.
The MS articles in question:
http://support.microsoft.com/?kbid=316309 (1619 error)
and

Hope this helps!

Unable to fully install itunes due to error message

I have been trying to install itunes and when I get about three quarters of the way in an error screen pops up telling me that I have an error writing to the file C:/Documents and Settings/All users/Application Data/.../GEARAspiWDM.inf and telling me I need to verify that I have access to this directory. How do I find that file and fix this problem so that I can fully install itunes?

an error screen pops up telling me that I have an error writing to the file C:/Documents and Settings/All users/Application Data/.../GEARAspiWDM.inf and telling me I need to verify that I have access to this directory.
Quite often those messages are caused by disk/file damage rather than a genuine permissions problem.
Try running a chkdsk over your C drive. There's instructions and a guided help in the following Microsoft document:
[How to perform disk error checking in Windows XP|http://support.microsoft.com/kb/315265]
Does the chkdsk find/repair any damage? If so, can you now get your iTunes install to go through properly?

Can't open itunes due to data execution prevention error

I am currently unable to open itunes due to a data execution prevention error. I have tried to clear temp files, uninstall and reinstall and nothing seems to work. I tried to disable DEP for itunes but nothing seems to work. Can anyone help me?

Try the following, one at a time:
1. First Repair QuickTime. START/CONTROL PANEL/ADD OR REMOVE PROGRAMS/highlight QUICKTIME, click REMOVE, then select REPAIR.
Now test your itunes and see if you still have this problem
2. If you have Codec installed, please uninstall it and test out your iTunes.
3. If all that fail, scan your system for possible Windows system file corruption:
Go to command prompt (START/ALL PROGRAMS/ACCESSORIES right mouse click "command prompt" and choose "Run as Administrator" (for Win XP-just click command prompt)
type in
sfc /scannow
let Windows fix any system files that need to be repaired.
Restart the computer if it did actually repair any files.
Open iTunes and see if problem resolved.
