We need to set some environment variables. Please have a look at the attached program modified from the same source as yours.
This looks good, we can replace the lyx.bat file with this shortcut.
hidecmd /LC_ALL=it_IT /AIK_DATA_DIR="C:\Programmi\LyX14\aiksaurus" lyx.exe I don't see the need to use "cmd /c".
Really? Have you tried? My understanding is that hidecmd hides the application (cmd) so if you run hidecmd lyx.exe, lyx itself will be hidden. Cheers, Bo
