Here is what I did today:
Uninstalled Nero and all of it's components.
Uninstalled Flac Frontend
Uninstalled Foobar
Uninstalled Trader's Little Helper
Reinstalled Nero
Reinstalled Flac Frontend
Reinstalled Foobar
Reinstalled Trader's Little Helper
Changed the Flac file icons from NeroMediaPlayer media files to display as their appropriate Flac icons
Only problem now is that the files are still listed as NeroMediaPlayer media files (I didn't even reinstall the Nero Media Player). How do I change them to list the appropriate type of file: Flac?
Like flipp said you are/were on the right track...to get rid of it saying neromediaplayer, when you're in folder options go to where you changed the icon, it is in the advanced tab...
If yours still says restore, hit restore, the advanced tab will show up in it's place. Then make sure the icon is still what you want, right next to the preview icon it should say neromediaplayer(for you, mine actually said neromixfiles)...it allows you to type in whatever you want it to read, I just typed 'FLAC', but you could type FLAC Frontend if you choose, or whatever for that matter.
That is now what it will read under the file along with the file size. After that is done now you can change what program "opens with" those files(and the restore tab will return).
Hopefully that does it for you, I had the same thing going on and I'm glad to get rid of the nero icons.
