It works for me. Let’s figure out what you are doing wrong.
This is the Target Update screen that you should post a clip of so that we can get a better idea of what you are doing. You can click the images for a larger view.
Note that you have a ( Save as ) option. Optionally, you can save the entire Media folder (or Sounds Folder) to a place of your choosing. Inside that Folder will be a setup.exe file that you can click to do the install. But that is just an option. The same folder is saved here;
C:\ProgramData\Phonak\Phonak Target\Phonak Target\WebUpdates\MediaInstaller
in a folder named U¦Target_Media_6.0 V=6.0.0
Now if I were to guess about what you might be doing wrong it would be ignoring this recommendation from Phonak;
Do you have any 3rd-party Antivirus crapolla running? If Yes, disable it and ask yourself why don’t you trust MS to protect your PC?
Rerun the setup.exe file in the following folder;
C:\ProgramData\Phonak\Phonak Target\Phonak Target\WebUpdates\MediaInstaller
in a folder named U¦Target_Media_6.0 V=6.0.0
btw> if you can’t see the ProgramData folder at all then you need to click the Hidden Data ckeck-box in file explorer/View, which itself can be hidden/un-hidden along with all your file explorer options by clicking a little down/up (^ v) arrow atop the file explorer screen, (or Control Panel/File explorer Options/View/Show hidden files).
