I have an Acer desktop running windows 7 64-bit that I have been trying to get fixed. The computer is failing updates and digging around, the permissions to the Windows Installer folder are all hosed up. That may be just one of the issues. I have done the normal cleanups, virus scans, and rootkit scans and then I stumbled across your program.
This keeps happening in safe mode with networking and even tried to run it from safe mode command prompt and still the same thing. Ran all the optional pre steps. After hitting start repairs, I get the starting repairs but then it fails 30 seconds later saying the current repair has failed to start 5 times and then all the stuff about doing it in safe mode...etc.
