Install error – 0x80070643 (Windows 10)

And, as usual, a super helpful error message that immediately gives you a hint where to start looking: online, on Google, and pray that someone somewhere had the same problem and for some reason there is some guy in the replies that knows what the actual issue is and how to solve it.

But you might as well just be an outlier and everything you find is threads from twelve years ago where some completely unrelated problem had exactly the same error code.
