Delgadoh, you are officially my favorite person on 2016. I know you posted this in 2013 but I just want to say THANK YOU!!! I was having the same issue my iPod Nano, 1st gen. It would not restore, just kept giving me the 1413 Error. I used the suggestion you made for Windows XP:
regsvr32 "c:\Program Files\iTunes\iPodUpdaterExt.dll"
It worked brilliantly, hurrah! I think my problem may have been that I am running an old PC that has no storage for music so I have all the iTunes files on an external WD 500GB hard drive. Maybe iTunes didn't know where to look?
Speaking of files in different places, I cannot see the Apple Mobile Device Service driver when I open Device Manager. My computer says it is installed and running, but it does not appear. I opened Task Manager, clicked on Services and then right clicked on Apple Mobile Device. It shows that the the executable path is still pointing to the old c:\ drive instead of the new one:
"C:\Program Files\Common Files\Apple\Mobile Device Support\AppleMobileDeviceService.exe"
Inexplicably the box with the executable file is greyed out. So even though I am the administrator, I can't point it to the correct drive!I know this is a wholly separate issue, but maybe you have a suggestion? Thanks again, you rock!
