Make sure you are logged in as administrator.
Open command prompt and type:
gem update --system
gem install watir
Output should be something like this:
C:\Documents and Settings\Administrator\>gem install watir
Successfully installed watir-1.5.x
Installing ri documentation for watir-1.5.x...
Installing RDoc documentation for watir-1.5.x...
You don't have to download the gem first. Ruby's gem system will automatically find it on the web, download it and install it. Watir's gem includes libraries, the unit tests and the rdoc, but not the examples or the rest of the Watir documentation. It is convenient for setting up a new machine to run Watir scripts that you've already developed.
The "gem update --system" command will update the gem system itself. This is required
to install Watir gems beginning with Watir 1.5.4 (April 2008).
Watir 1.4 was released in August 2005. If you are upgrading from it,
see these notes.
This page is current for release 1.5.6.
