x64

From iMacros

iMacros includes a 32-bit and 64-bit version of the Scripting Interface. The x64-interface allows you to run iMacros directly from any 64-bit application on Windows x64 systems. For example, you can use it with ASP.NET with IIS running in 64-bit mode.

The use of the 64-bit version requires no code changes. After you install the 64-bit version of the Scripting Interface, 64-bit applications automatically access the 64-bit version of the interface. 32-bit application continue to work on the same system, as they automatically continue use the 32-bit version of the Scripting Interface.

Note about VBS scripts: If you start a VBS script from a Desktop shortcut or Windows Explorer (= 64-bit applications on 64-bit Windows!) the VBS script runs in 64-bit mode. But if you start the same VBS script from a 32-bit application such as Total Commander the VBS scripts runs in 32-bit mode. This is a convenient way to test both versions of the interface.
