Solution
You need to register AutoIt. In a command window, navigate to the directory where you've put AutoIt and type:
regsvr32 AutoItX3.dll

Thank you for your suggestion. When I ran in the cmd prompt it displayed following message window "The module "AutoItX3.dll" failed to load.

Can you help please. Thanks.

Try pointing to where the file actually exists, i.e.


regsvr32 c:\ruby\lib\ruby\gems\1.8\gems\watir-1.6.2\lib\watir\AutoItX3.dll

I saw a similar issue after upgrading a system to Windows 7.. Pretty sure it had been working before that (but job duties had me away from using watir for about 6 months)

registering the DLL took care of it.

FYI... I discuss registering the AutoItX3.dll using Ruby on my Blog if anyone is interested.

Did not register on my Win 7 64 bit box either. Tried manually and got error 0x80070005 which meant it needed to be done as root. As root it registered. Getting watir-1.6.5/lib/watir/dialog.rb:38:in `click': Watir::Exception::UnknownObjectException

you don't need to register as root, but as administrator.

What I did was go to the :

C:windows/SysWOW64/
folder
right click on "cmd.exe" => run as administrator.

type :
regsvr32.exe "FULL_PATH_TO_DLL"

example :
regsvr32 c:\ruby\lib\ruby\gems\1.8\gems\watir-1.6.2\lib\watir\AutoItX3.dll


The key part is being using the cmd window as admin
