I recently (like yesterday) installed 64-bit Vista Enterprise on my desktop and for some reason cannot get my iPod Touch to get detected by iTunes. I downloaded iTunes 8.0.1, 64-bit version (iTunes80164Setup.exe) and installed it, but during the installation it states that it is rolling back copying files. It does complete the installation, but at the end there is no Apple Mobile Device Support installed, this causes iTunes to state that the required software is not installed when I plug in my Touch. I have completely removed the components it did install and tried again, but the same thing occurs. Extracting the contents of the iTunes setup and running the AMDS installer still does the same thing. If anyone has any thoughts or ideas, they would be greatly appreciated as I really need to sync my Touch.
