The problem is that Windows 7 does not allow some entries to be removed even though they are bad entries, so those entries (in your case, 193 entries) are not removed and are found the next time that you run RegVac. Windows 7 does allow other entries to be removed and so RegVac should still be used to clean those.
I do not know how the A1Click folder ended up empty. I have never heard of that. RegVac cannot remove it.
I have not experienced or heard of any problems with A1Click and Windows 7.
