Please read the attached file.  I have made the document easy-to-understand and I have thoroughly tested and applied the method for the last 5 years without a single failure.

No other option.  Reboot the stack and re-run the Install Mode command.

Yes, that's the only option...i have also seen same on cisco's bug solution.
