Unable to Register ActiveX Controls on 64-bit Windows

When attempting to manually register an ActiveX control on 64-bit Windows, an error is displayed indicating it is not an executable file and no registration helper is registered for this file type.

More Information

On 64-bit versions of Windows, the \windows\system32 folder contains 64-bit executables and you cannot register 32-bit ActiveX controls using the 64-bit version of regsvr32.exe. A 32-bit ActiveX control should be copied to the \windows\syswow64 folder, and the regsvr32.exe utility in that folder should be used to register the control.
