How To Install Unetbootin 494 Linux

Unetbootin
I am trying to install on my Linux Mint (12 - KDE) machine and it will not run. I downloaded the Linux version of it (downloads as a unetbootin-linux-581 file) and set its permission to chmod +x unetbootin-linux-581. I've tried running it every way I can think of:. Double-clicking it from the dolphin file manager. Running./unetbootin-linux-581.
Running sh./unetbootin-linux-581. Running unetbootin-linux-581.sh Nothing seems to be working. So I downloaded it on my Linux Ubuntu (12.04) machine, in case UNetbootin doesn't run on Mint for some reason, and am getting the same results.
How do I run it, or what do I need to do to be able to run it?!? Thanks in advance!
Okay, start by installing gparted and ntfs-3g: sudo apt-get install gparted ntfs-3g; Open gparted: sudo gparted & If your USB is mounted, unmount it. Format it with an MBR partition scheme, and a single NTFS partition. Right-click on the partition and give it the 'boot' flag. Make sure it is executable, then run it: chmod +x /Downloads/unetbootin-linux-494; /Downloads/unetbootin-linux-494 & Choose your Windows ISO as the source and your USB drive partition as the destination. Click Okay and let it complete.
That should do it, let us know if you have questions along the way.
