Use for Apple Remote Menu Button in 10.7?

I believe you mean Front Row.

Front Row works in Lion if you do the following.

1) Copy the required files from a Snow Leopard install, or get them from somewhere. This is more than just the Front Row app from the Applications folder.

2) Set up a local share of your iTunes library.

Once Front Row is (re)installed, the remote will work swimmingly and Front Row will launch.

However, you'll notice it won't find your music library. Pictures and videos should work fine. However, in order to get your music, you'll have to "share your library with yourself", go to sources on the main menu and voila, your music is there, albeit with missing album art.

If you can, I'd suggest getting it directly from a SL install, if you have one available.

I'd suggest reading this:

You'll want to read the comments in the second link as the article itself has some errors

Do you have iTunes open? Is sharing enabled in iTunes?

Try the very first command listed in the article and see if it works for you then.

If that works, it should work "permanently" by using one of the commands in the comments. I suggest the one posted by "richiesmit".

Ahh, that may not quite be the solution for you then. I'm afraid there isn't any other way at this point.

In theory, it SHOULD work. I'm not sure if Front Row was able to connect to password protected shares pre-Lion/iTunes 10.4.

But assuming Front Row could read protected shares, then perhaps the conflict lies in how the shares are protected in newer versions of iTunes.
