OpenMAFF : Error - Application not found

[heX16]

I place OpenMAFF.exe in folder "C:\1" and place MAFF in some folder. Run in console: "OpenMAFF.exe 1.maff"

My default browser config (from registry): Reg Add "HKCU\Software\Classes\FirefoxURL\shell\open\command" /f /ve /d ""D:\NetDrive\AppsPortable\Firefox\Firefox.bat" -url "%%1" " Reg Add "HKCU\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\http\UserChoice" /f /v "Progid" /d "FirefoxURL"

Can add to the config the ability to specify the path to the browser?
