Need help with installation in BATCH file

[jrt.admin]

I push the installation via BATCH file, everything works well, I had some trouble at the beginning for forcing the software to be installed in x64 (Silent mode), but a great samaritan help me in this forum with the /os.arch=x64 that works well.

Now my problem is very tiny, I want to add a desktop icon but my attemps didn't work. I tried /MERGETASKS="!desktopicon" but without any result, I've also tried with no ! and with /Tasks and no result. Anyone knows which command to use?

By default, the installer of the free version creates a desktop icon and I just checked that it's the case in silent mode.
If you add the parameter [font=courier new]/MERGETASKS="!desktopicon"[/font] to the installer command, there won't be any icon.
