Cannot install Apple Mobile Device Support

i was also dying. i couldn't get anything to work for my IPhone6 for days. till i tried the link you put up this work for me. the first time it did not work as i installed it completely. so i tried it a gain and this time i checked iTunes every time i installed each download. this time it worked. i did not finish the entire installation. by checking after each down load it bugged out the problem by itself. mine ended up being a corrupted driver. hopefully this work for anyone in the same situation.

you will want to do clean uninstall of all apple products IN THIS ORDER:

1. iTunes
2. Apple Software Update
3. Apple Mobile Device Support
4. Bonjour
5. Apple Application Support (iTunes 9 or later)

Then reinstall. Best of luck.

Rip it up & start again as given above.

If it still fails to install properly you could try downloading and installing 7-Zip (free) then unpack the iTunes installer into its components using 7-Zip, and install the missing components individually. They may still fail to install but you may get more useful error messages as to why not.

Try again. Some people have had success after going through the complete uninstall, delete selected folders, reboot, install as admin steps several times.

I don't know about Youshigi, but I have been deleting and reinstalling everthing to do with itunes, carefully following the instructions provided, at least weekly ever since the itunes 11.1.4 disaster, and installing Apple Mobile Device Support still gives the error message above. I had high hopes of version 11.2, but it's just the same.

Simply deleting and reinstalling over and over again is no answer. Is there no expert with a better idea? Or do I have to buy a new pc?

What about a standalone install of AMDS after unpacking the installer? Have you tried creating a new admin account and signing into that to perform the installation?

Thanks. I've tried a standalone installation of AMDS quite a number of times without success. The idea of creating a new admin account is a new one on me. I don't have time to try it immediately, but hopefully will do tomorrow. I'll come back here after that.

Finger crossed.

Should it not work, what error messages, if any, are generated when you try to install that component?

Sadly, this proved as futile as everything else I've tried - and in exactly the same way. As part of the itunes package (after, obviously, following your instructions in every detail) AMDS installed (as far as I could see from the installation box) virtually all the way, and then rolled back without comment. Installed on its own from the .msi file, it installed and then rolled back and generated the usual message: "The installer encountered errors before Apple Mobile Device Support could be configured".

My belief remains that the process of removing 11.1.4 damaged something, somewhere. I've run chkdsk and scannow, neither of which show a problem.

Presumably, there is something in Windows which records (or could record if asked) what's going on during an installation, which would allow an expert to see what goes wrong and where. My best offer, looking at the Event Viewer log for when AMDS was (not!) installing, msiInstaller generated a series of warnings each time. Most were "The application tried to modify a protected Windows registry key..." followed by an address, and one at the start each time said that "...feature 'SoleFeature' failed during search for component...". But I'm not really sure what to look for or competent to understand or deal with it.

I don't usually let myself be beaten by the computer - and I don't often give up. But this looks increasingly hopeless!

If you want to generate log files try one of the following commands. These have both the .msi files and the output logs located at the root of the C: drive but you can edit the paths to taste. The second option switch is slash el star vee and generates a verbose output log.

msiexec /i "C:\AppleMobileDeviceSupport.msi" /l*v "C:\Log_AMDS.txt"

msiexec /i "C:\AppleMobileDeviceSupport64.msi" /l*v "C:\Log_AMDS64.txt"

I finally got round to this. The full log is 1.29 MB, and I do not have the expertise to interpret it. On the off chance, I searched through it for "error". At the start, it recorded a number of processes that it couldn't shut, all the way through there were instances of "won't patch; no existing file", and after 25 seconds or so there was a series of error messages, which, if I could've worked out how, I would have pasted in here. It then tried to roll back. It also doesn't seem to be possible to attach the log... I assume there's a way of doing both that I have't found.

Notsof

I'm not certain that I'd know what to look for either. 😟

If you open the log in something like Notepad++ that can handle large files you should be able to copy out a few snippits that you think might hold useful clues..

There was a new build of iTunes (11.2.2) on May 28th so have you been using that installer or an older one?

There is a chance that you can use the Microsoft Program Install and Uninstall Utility (AKA MS Installer "Fixit") to force through the installation of the .msi.
