Dear monk, to get rid of that error you need to install AutoIt application. Either a licensed ware or a free version. Probably you can get it from: (https://www.autoitscript.com/site/autoit/downloads/) Now if you are interested in a portable version, probably you can get it from: (https://softwarespot.wordpress.com/code/autoit-portable/) and its script editor from: (https://www.autoitscript.com/site/autoit-script-editor/) Unless you install AutoIt application the .dll files will not be registered and the code that uses Win32::IEAutomation might not work. Its better to go for normal install than to go for portable version as the .dll files need to be registered with OS. Once you install the AutoIt application, I am very much sure that Win32::IEAutomation will work flawlessly with IExplorer 8 and below. Click method wouldn't work if IExplorer version is 11. Didn't try using it on IExplorer versions 9 and 10
