I too have had countless failures in the update and have tried the oupdate_m.exe update as recommended by tech support. I think it is a USB driver problem. in Windows, my device manager lists it under Sound Video and game controllers as Timefacor Pedal but it has a yellow warning exclamation sign. The general tab indicates the driver cannot start and the details says it a MS Driver 6.0.6002.18005 and the Details says it a USB audio device. If Eventide would release a new USB driver so that the Timefactor would be recognized and installed properly, I think this would fix the majority of the update issues.
My 2 cents
