uninitialized constant Windows::API::Error (NameError)

[Dennis I.]

I tried installing Watir at home a while ago and kept getting an
error. I followed some instructions here from a different discussion
that mentioned installing and reinstalling some gems.
That didn't work. And today I tried again. Here is the error that I
get.

Here is the code until where it gets stuck:

require 'watir'

time = Time.now.to_s
puts "Test executed on "+time

test_site = "http://www.google.com"

ie = Watir::IE.open(test_site) # this is line 22

Some more details:

ruby -v
ruby 1.8.6 (2008-08-11 patchlevel 287) [i386-mswin32]

gem list -l watir
watir (1.6.2)

That is correct. I ran into same issue and got it resolved with same
command.

Had the same issue on Windows XP test machine here when upgrading
framework to use watir 1.6.2 and Ruby 1.8.6-26
We had windows-pr-0.9.6.gem installed with watir 1.6.2

I upgraded to following gems and it's fine
windows-pr-1.0.2
windows-api-0.3.0.gem
win32-api-1.4.0-x86-mswin32-60.gem

fyi: We maintain a private cache of gems here so I can prepackage
installation on our test machines here with rake tasks

[karimnumerouno]

this is the solution

perform
gem install win32-api --platform x86-mswin32-60

and then

gem install windows-pr

performing the above steps worked for me
