Does ESET Online Scanner work with 64-bit versions of Microsoft Windows?
Yes, ESET Online Scanner works with x64 (AMD64 and EMT64) versions of Microsoft Windows—it does not work with Itanium (IA64) versions of Microsoft Windows. The ESET Online Scanner is a 32-bit application, which means it must be run through in the 32-bit version of Internet Explorer, and as an Administrator (see Q7, above). To do so, right-click on the Internet Explorer (32-bit) icon in the Start Menu and select “Run as administrator” from the context menu.
