the icon does not launch.

Just need to do :

You are on the right track, just need to delete the desktop shortcut and zdesktop folder, and then create it again: Do each of the three lines one at a time:
cd ~
sudo rm -rf zdesktop Desktop/zd.desktop
/opt/zimbra/zdesktop/linux/user-install.pl

How do I use Unetbootin to make a bootable Windows USB installer?

After I ran Unetbootin and isntalled Windows on it , whe I boot on PC it starts a countdown and nothing happens:

This Fix worked:

• Format your USB as FAT32 in GParted
• Open UNetbootin and get it as far as the stage where it brings up the USB partition to install to e.g. /dev/sdb1 - Don't install the ISO, though
• Leaving UNetbootin open as is, reopen GParted
• Format the USB in GParted as NTFS
• If GParted doesn't automatically add the "boot" flag, add it yourself
• Now, go back to UNetbootin, which you've left open in the meantime, and click OK

Doing so, UNetbootin will think you are using a FAT32 partition and will let you use NTFS format.
EDIT: at this point UNetbootin complained the USB device was unmounted. Keeping UNetbootin open I ran sudo mount /dev/sdb1 /mnt. Then I hit "OK" on the still-open UNetbootin. It wrote the USB image to the USB.
