There is another set of steps that can resolve 1402 and 1406 errors when installing iTunes for Windows that involves manually editing the computer's registry file.

Important: Before starting these steps, make sure you are comfortable with the steps to be taken and the inherent risks involved in making changes to the Windows registry. Making mistakes in Regedit can cause strange behavior and can even prevent Windows from starting. It is strongly recommend making a backup copy of your Registry before making any changes to it.

1. In Windows Vista, on the Start menu, click All Programs, click Accessories and click Run. In Windows XP and Windows 2000, on the Start menu, click Run.
2. Type in Regedit and click OK (this takes you to the Registry Editor).
3. Click the reveal button (arrow or + sign) next to HKEY_LOCAL_MACHINE.
4. Click the reveal button next to SOFTWARE under HKEY_LOCAL_MACHINE.
5. Click the reveal button next to Classes.
6. Click the reveal button next to ".cdda."
   1. Select the .cdda key in the left hand list.
   2. On the File menu, click Export.
   3. In the dialog that comes up, make sure the "Selected branch" button is selected for the Export Range.
   4. Save the file with a name and in a location that will be convenient to find, such as "cdda settings" saved to the Desktop.
To save (make a backup) the original contents of the registry, so that you could go back to your original state if necessary:
7. Find the heading OpenWithList."
8. Right-click on OpenWithList.
9. From the pop-up menu, click Permissions.
10. Click the Add button. The Select Users or Groups dialog opens.
11. Click the Advanced button. A larger dialog also labeled Select Users or Groups opens.
12. Click the Find Now button.
    The Find Now button should list all of the users.
13. Select Everyone in the list of users.
14. Click OK. This closes the second Select Users or Groups dialog. The first Select Users or Groups dialog now lists Everyone in the Enter the object names to select field.
15. Click OK in the dialog box now on top. This closes the first Select Users or Groups dialog.
16. In the Permissions for Everyone section, select the Allow check box for Full Control. Click OK.
17. Right-click OpenWithProgIds and repeat steps 9-16.

Close Regedit, restart the computer, and try the install again.

Restore the Registry

To restore the registry to the original settings, follow these steps:

1. Find the file saved from the registry (as noted in step 6 above, i.e. “cdda settings” on the Desktop) and double-click it. If Windows needs your permission to continue, click Continue.
2. Click Yes.
3. Click OK.

This will overwrite the edit and return the registry to it's original state.

Note, that this file is just a backup. It can be deleted at any time when you are finished editing the registry and have installed iTunes successfully.
