Use this instead:
start "MyTitle" "<path>test.exe" /55512340453
When "start" sees the first quote, it treats it as a window title.
Apparently this is only supported in XP and most likely Windows 2000.
Windows 9x does not support the title option. If you use quotes around the
path and don't include any option, then you have to use the title option as
well. Here are some valid examples:
start "" "<path>test.exe" /55512340453
start /i "<path>test.exe" /55512340453
start /normal "<path>test.exe" /55512340453
Here is what Windows 95/98 show:
Runs a Windows program or MS-DOS program.
START [options] program [arg...]
START [options] document.ext
/m[inimized] Run the new program minimized (in the background).
/max[imized] Run the new program maximized (in the background).
/r[estored] Run the new program restored (in the foreground). [default]
/w[ait] Does not return until the other program exits.
