Permission-denied error while using Lilypond 2.12 with MikTeX

[Ambareesh Pandit]

I am attempting to use LilyPond in Windows XP with MikTeX but am getting the following error:

C:/Program Files/LilyPond/usr/share/lilypond/current/scm/backend-library.scm:115:15: In procedure delete-file in _expression_ (delete-file pdf-name):

C:/Program Files/LilyPond/usr/share/lilypond/current/scm/backend-library.scm:115:15: Permission denied

Below are the steps I took within MikTeX to get to this point.

1. Edit -> Preferences -> Typesetting tab

2. Clicked "+" within the "Path for TeX and related Programs" section.

3. Navigated LilyPond installation's bin directory and hit ok.

4. Clicked "+" within "Processing Tools" section.

5. Added values below to text fields and hit ok.

Name: LilyPond

Program: lilypond.exe

Arguments: $fullname

After this I open my *.ly file, select "LilyPond" in the dropdown box next to the Play button in MikTeX, and get the error I have pasted above.  Has anyone been able to successfully use LilyPond in MikTeX?  Does anyone know what the message above means or how to get around it?

Thank you.
