Driver ? Installation for Leonardo

Using Arduino Installation & Troubleshooting
#1

What is the way to install a Leonardo. I have installed Arduino 1.06 and followed all available instructions. Everything looks ok BUT the Upload of Blink fails and the Windows 7 comes back with another attempt to install a driver. Finally Uploading quits with the following error message.

Problem uploading to board. See Http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.
Binary sketch size: 4692 bytes (of a 28,672 byte maximum)
Found programmer: Id = "B@) " type = .
avrdude: error: buffered memory access not supported. Maybe it isn't a butterfly/AVR109 but a AVR910 device?

I tried the Guide for Uploading problems to no avail.

Could you try Arduino IDE 1.5.8 BETA. That version has the serial communication in a different way.
There is also a 'driver' folder when you download it, and there is a *.exe that installs the newest drivers.

I have a few problems with Leonarde sometimes, I have to disconnect or choose another COM port. But in Windows 7 I have the least trouble with the Leonardo.

Tried IDE 1.58. Still doesn't work. I'm coming to the conclusion that the Leonardo is a loser.
