Watir issue with AutoIt on Vista 64 bit

Installed Watir (v1.6.5) on top of Ruby (v1.8.6) on my 32bit WinXP and
64 bit Vista systems. Ran into way too many issues trying to use Ruby
1.9.1 (64-bit) and Watir(v1.6.5), so degraded to try these older
versions, as Watir site recommends.

Are versions of Watir (v1.6.5) and Ruby (v1.8.6) for Vista 64-bit
available? If so where?

This is the four line program that run OK on 32bit XP, but fails on 64
bit Vista.

require ‘Watir’
browser=Watir::Browser.new
browser.minimize # Fails on this line
browser.close

Here’s the irb session on the 64-bit Vista system:

C:>irb
irb(main):001:0> require ‘Watir’

irb(main):002:0> browser=Watir::Browser.new
