Foreseen back in 2009 by Eric Law’s IEInternals:
“One day, 64bit IE might see a lot more use, as 64bit systems take over and 64bit add-ons become available. Time will tell.”
The day has came for WOT, which is now also available for the 64-bit Internet Explorer!
When you download WOT, your browser’s version is detected and you will automatically get the right version of WOT. Note that the WOT add-on has always worked with 64-bit versions of other browsers.
