FX wont launch-I' edited-FirefoxPortable.ini

HI awesome progam !

I' was hoping I' could find out why the launcher wont work after I' edited the FirefoxPortable.ini file

I'm receiving this error error message.

"firefox could not be started,you may wish to re-install to fix this issue"

--
I' changed the firefox.exe executible to foxy.exe
F:\FirefoxPortable\App\firefox\foxy.exe

I' placed the edited FirefoxPortable.ini into the same directory as the launcher file FirefoxPortable.exe.

*:\FirefoxPortable\FirefoxPortable.ini

I' used lower case characters to edit the FirefoxPortable.ini file

help what am I' doing wrong?
