hi

I cannot locate the adi and SC Info folders that is mentioned in the solution that comes up automatically when logging onto itunes. Anyone know exact location in WIN10.? Some users are saying this step doesn't work anyway but I would like to try.

"On a PC

1. If it's open, quit iTunes.
2. Press the Windows key on your keyboard. If your keyboard doesn't have a Windows key, press the Control (Ctrl) and Escape (Esc) keys on your keyboard.
3. Click on the magnifying icon or search field. In the search box, type

   %ProgramData%

   , then press the Return key.
4. Show any hidden files:
   Windows 10: Click View, then select "Hidden items."
   Windows 8: Click View, then click Options. On the View tab, select "Show hidden files, folders, and drives."
   Windows 7: Click Organize, then "Folder and search options." On the View tab, select "Show hidden files, folders, and drives."
5. Open the Apple Computer folder, then the iTunes folder.
6. Delete the adi and SC Info folders: Right-click each folder and choose Delete from the menu.
7. Restart the computer.
8. Open iTunes and try to make a purchase."

This is a Windows error message. Type it 'iTunes error 45054' into Google where there are multiple mentions.
