When installing or uninstalling iTunes, some people will find that the installation or uninstallation fails, indicating that the specified account already exists. How to solve this problem? This problem occurs because iTunes was installed on the original computer and was not completely uninstalled when it was uninstalled, or for example, I reinstalled the new version of iTunes when I had a system backup. Due to various reasons, the system was restored to the previous backup, resulting in iTunes problems. Therefore, I need to completely uninstall the components installed with iTunes installation.

Method 1 (personal feeling unreliable, using this method has not been successful), open the computer's control panel, find "programs and features", find "Bonjour, Apple application support (32 bit), "iTunes ", "Apple application support (64 bit)", "Apple software Update" , "Apple Mobile Device Support"these software, uninstall

Download the new iTunes and change the suffix "exe" to "rar"

Then open "itunes.rar" with compression software, extract it, find ApplessoftwareUpdate.msi, double-click to install, and then install

If you still can't solve it, you need to delete iTunes related content in the registry, press windows+R to open "Run", enter "regedit" to enter the registry, click "Computer" in the upper left, press Ctrl+F, check "Full word match", search iTunes, Apple Software Update (no spaces), Apple Software Update (spaces), each item is deleted to the prompt "Registry search completed"

Finally, find the following folders and delete them one by one

C:\Program Files\Bonjour

C:\Program Files\apple

C:\Program Files\iPod

C:\Program Files\Common Files\Apple

C:\Program Files\Program Files (x86)\Bonjour

C:\Program Files\Program Files (x86)\apple

C:\Program Files\Program Files (x86)\iPod

C:\Program Files\Program Files (x86)\Common Files\Apple

Method 2 (I have used this method several times and can successfully solve the problem), find a software called "WindowsInstallerCleanUpUtility" from the Internet to download and install, which is a software that Microsoft has released to clean up the Windows Installer configuration information of the program. The installation path cannot be selected when installing this software. After installation, desktop shortcuts will not be generated, and it will be automatically installed to disk C. After installation, it can be opened and run from the default path of disk C:\Program Files (x86)\Windows Installer Clean Up\msicu.exe. The software is very small and can be uninstalled immediately after use.

After opening the software, uninstall all components of itunes in the configuration information, select "Bonjour, Apple Application Support (32-bit), ""iTunes ", "Apple Application Support (64-bit)", "Apple Software Update" , "Apple Mobile Device Support" These components, click "Remove" below to uninstall.

After uninstalling the component, restart the computer. If you install itunes immediately at this time, you will find that it still cannot be installed, and a long series of error messages such as "unable to press keys..." will appear.

We also have to open the registry modification permissions (first you have to use the administrator account), press the windows+R key to open "Run", enter "regedit" to enter the registry, find HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData\S-1-5-18\Components

Right-click on "Components"-"Permission"-"Advanced"-"Owner"-"Select yourself"-Check "Replace subcontainer and owner"-"OK"-"OK"

Select your administrator account in Components-Permission-Advanced-Permission Item, and check Replace all child object permissions with permissions inherited from this object-OK-OK below.

At this point, the problem has been solved and itunes can be installed normally.
