MCPR.exe gives McClnUI.exe - Entry Point Not Found error on Windows XP

[nnnnmm]

Trying to use MCPR.exe on an old, but servicable Windows XP laptop.

Running it as Admin user, getting an error box with

The procedure entry point CancelIoEx could not be located in the dynamic link library KERNEL32.dll. 

Just downloaded MCPR.exe today.

Any ideas anyone?

Thanks
