So...Don't know if anyone at Avast is still paying attention to this thread, but nothing has improved with the problem being dealt with through this thread.
The following statement was confirmed as being dealt with yesterday evening by my Sister:
"You downloaded aswClear to your desktop. You went into safe-mode (Windows looked weird, and probably had text in each corner warning you that you were in safe-mode. Properly being in Safe-Mode is required). You launched aswClear. one-by-one you selected each of the 'free' versions (4 thru 7) from the drop-down. For each version you selected, You hit some button to tell aswClear to do its thing. After that was done, you restated the computer, launching Windows as normal, and failed to install Avast Free Version 7."
Latest Log-file from that venture is attached.
