To resolve this problem, obtain the latest service pack for the Microsoft .NET Framework 1.1.

I have exactly the same issue when trying to install iTunes on my new windows 7 laptop. I have tried uninstalling and re-installing these apple software multiple times, with internet cut-off and firewall/anti-virus turned off using administrator account, cleaned up registry with CCleaner, etc., and still got this same error.

Now I have at least a partial fix: after plugging in the iPhone, in Device Manager, under "Universal Serial Bus controllers" there would be an Apple Mobile Device with a yellow flag. Right click that item and choose Update Driver Software, then choose "Browse my computer for driver software", then choose "Let me pick from a list of device drivers on my computer", then choose "MTP USB Device" instead of the default "Apple Mobile Device USB Driver".

After that, at least the laptop can recognize this iPhone as a USB device, and starts charging it. Can also import photos/videos. Although iTunes still doesn't recognize the iPhone and can't sync it. But this is as far as I get.

I know how to fix it! Yet this fix is not anywhere on the internet. Just go to services again, and right click apple mobile device, then properties, and then on logon you need to create a new account with admin privilage, and then assign the new admin account to the login tab, apply the changes, and then start the service. It worked for me, and I am able to use my iphone again. Note that you cannot choose the same account you use wether it's admin or not, as it will come with the 1609 error. I hope it works for the rest of you guys.

Best of luck,

Getting rid of the Apple conponents in that order.

I ran CCleaner for good measure, then re-installed iTunes. It installed properly this time

Thank you, I was getting the same error had reinstalled iTunes 3 times. I removed ALL the Apple components and ran CCleaner I was then able to get iTunes to install properely. Again Thank You

@ pcfixer1. Can't thank you enough for your input and fix below regarding the "apple mobile device failed to start" error 1503. After a full week scouring the web, attempting or applying fixes to no avail, your resolution was the one that worked. The only thing I'd like to add, if I may, is that I was able to assign the only admin account (mine) to the "Login" tab and didn't have to create another Admin account in its place. All I simply did was assign my User Profile name and password for the current account, applied it as you instructed and was immediately then able to start the "AMD" service. Absolutely BRILLIANT!

Unfortunately, no. If you run it under the same admin account, the error will still happen. Maybe try assigning it to a user that is always logged on that is a service, like TrustedInstaller that has full admin? I have no current Window machine to test this on, but try a service that acts as a "user".

Let's make sure all come here and read this fix. It is an unknown fix and this issue is still unsolved in 99.9% of the web, and the only actual fix is here. I used Trial And Error to find this working solution. Well if you managed to reput your user account in the Login tab, then perhaps the OS is confused and needs a manual refresh of the service to work. Also if that re-adding account does not work, try assigning the hidden "Administrator" account that is not visible in login so that this works at system level and not at GUI level.

Apple posts fixes that do not work for the service problem! People that say "Oh i fixed it with CCCleanerwhatever are true fixes, but for 80% installing and using ccc whatever is hard and is better to not handle all those installations and prefer that login tab fix I postes. Cannot believe no one ever tried that?

Hi pcfixer1. I completely understand except that I haven't encountered a single error using the method I described using your "fix". Maybe I was just lucky to be able to use my current Admin credentials and not have to create another "Admin" account just to assign to the AMD Service. Thanks again!

By the way, I just wanted to be clear on the fact that your method worked 100%. The only thing I did different was that I assigned my current credentials to the AMD Service rather than creating a new one. A complete shot in the dark, but it worked for me......80) Thanks!

OMG dude!!! I never reply to messages on the internet unless I am incredibly happy lol

I have also been struggling with this for months. I read countless of websites, links, downloaded software, call apple support, uninstall and reinstall itunes several times, followed the correct steps, tried to restart apple mobile device going to services etc etc etc.

I was on the phone for about an hour and a half yesterday with apple and they still could not figure out what the problem is. This solved it instantly. Thanks again dude!!!!!!!!!!!!!!!! 🙂
