+I have tried to uninstall Apple Software update but it said "The feature you are trying to use is on a network resource that is unavailable"+
🙂 Thank you kindly.
Download and Install the Windows Installer CleanUp utility. Run the utility, find "Apple Software Update" in the list of programs in CleanUp, select the "Apple Software Update" entry, and click "Remove".
Description of the Windows Installer CleanUp Utility
Next, we’ll manually remove leftover program files and folders.
1. On the Start menu, click My Computer (or double-click My Computer on the Desktop).
2. In My Computer, open Local Disk.
3. Open Program Files.
4. Right-click on the Apple Software Update folder and click Delete from the shortcut menu.
Restart the PC and try another iTunes install. Does it go through properly now we've got the old version of ASU scraped away?
