Has anyone tried it yet? Vista will not allow me to delete folder "C:\Program Files\Common Files\Apple\Mobile Device Support" another wonderful upgrade from Microsoft that complicated or failed more than it improved. Apple Tech I spoke with for hours did not know about this. Or he knew of problem deleting folders in Vista. We could not resolve and higher up Techs could take a week to even respond.
Miracles do happen. I found another post regarding how to perform Device Firmware Upgrade. I connected iPhone and low and behold iTunes identified phone and asked if I wanted to upgrade to 3.0. I declined that upgrade as everything is working just fine now and plan to wait on 3.0 quite sometime. I did nothing new today I just connected and it worked, who know why or what caused problems prior two days.
This seems like the exact thing I needed, but it wont let me install apple mobile device. It says installer encountered errors before completing. And after I installed itunes, there wasnt even a folder called apple mobile device in programfiles/commonfiles/apple/
So I had nothing to delete, and just extracted the applemobiledevice.msi from the 8.1.1 installer and tried to use that, and the errors continue. It seems no matter what I do its an endless loop of installation errors everyway around.
I was wrong as once again iTunes 8.2 is back with error. Iphone detected but cannot be identified. I tried multiple shutdown and start up combinations between PC, iTunes and iPhone all to no avail. There has got to be some conflict here and it seems to be Apple software with the issue not my iPhone or my PC. They can and did work once since the upgrade nothing changed to fix it Saturday and again nothing done that should cause it to fail Sunday and Monday.
It wont allow me to install AMDS at all. I don't currently have AMDS installed as far as I can tell, its not in my add/remove programs and not in programfiles/commonfiles/apple there is no folder for AMDS even there. When I install itunes it does not install AMDS at all for me, and when I tried to extract that older AMDS as this solution says, it will not allow me to install (The installation encountered errors try again later).
Your basic suggestion actually worked for me. But this is what I did for others who are having issues removing/installing etc.
1. Download the latest iTunes 8.2. You should end up with a file iTunesSetup.
2. If you dont already have WinRAR, download free copy from http://www.rarlab.com/ and install.
3. Right click on iTunesSetup and choose "Extract" to somewhere you know. eg C:\itunetemp
4. Open up folder where you extracted iTunesSetup and double-click applemobiledevicesupport.msi
5. It should ask you if you want to repair or remove... choose remove.
6. REBOOT your PC.
7. Go back to where you extracted iTunesSetup and double-click applemobiledevicesupport.msi and go through the install.
8. Plug in your iPhone.
If all is well iTunes should automatically start and start syncing your iPhone.
Mine does not give me that option to remove/repair, which I'm pretty sure is because I don't actually have any applemobiledevice installed, and that kind of turns this problem into an endless loop of not being able to get it installed. I can't just upgrade/repair/remove because I don't have one installed, and I can't just install one because it says the installation encountered errors.
I am having same issue - my iphone is on 3.0, updated on a work machine, which dowlnloaded latest version of itunes and works fine. Issue is with home pc, which when downloading, it won't install the new version of amds - goes to "rolling back" action.
Followed the advice above, ie removing and then installing older version via a winrar extract - the older version still works and installs. Then, when I try to install the newer version of AMDS with 8.2.23, it just won't load it - it encounters an error before updating..........as you are, I seem to be going around in circles. Have you found a solution, or does anyone know one??!!
Erik, I'm using Windows 7 RC1 x86 on iMac with Bootcamp and I'd struggled with this for hours.
Removing AMDS that came with iTunes 220.127.116.11, installing the AMDS that came in iTunes 8.11 and then reinstalling the version from 18.104.22.168 again worked a treat. Thank you!
BTW, what made you think to use AMDS from iTunes 8.11?
I'm having this same issue, and I attempted your suggestion but could not delete the folder: C:\Program Files\Common Files\Apple\Mobile Device Support. It says it could be encrypted or full. Do you have any insight into this? I've attempted this whole process about four times, (i.e., updating to 8.2); and it never recognizes my iPhone. I always have to back down to 8.1.1 and uninstall/cleanup everything. So, I'm attempting your steps now. The only hang-up is the fact that I can't delete the above folder. I am the only user as it's a home computer. Any input you may have would be wonderful.
Try the old DOS trick or renaming that folder instead of trying to delete it.
In WinExplorer, right-click > rename, and change it to something like
C:\Program Files\Common Files\Apple\Mobile Device SupportDELETEME
Sometimes the OS gets confused and will let you rename something, but not delete it.
