No, I am not troll, and name is from actual chiptune, check it out
I too have used countless times the installers/unistallers, but those two were exceptions. The driver was from the official site of Dell. I dont blame them at all, since this event seemed like a complication (happened the second time I run the istaller).
As far as I understand, installers/unistallers in windows are built on the same foundations; the core of them is almost the same, so these two events were triggered by something outside the installer/unistaller.
Indeed, these are very rare phenomenons, you must be very (un)lucky to see them :P!
