iMacros V6.30 and later includes a native 64-bit Scripting interface.

The use of the 64-bit version requires no code changes. After you install iMacros it registers both, the 32-bit and 64-bit versions of the Scripting Interface with Windows. Thus 64-bit applications automatically access the 64-bit version of the interface. 32-bit applications continue to work on 64-bit Windows, as they automatically 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.
