install_program deleted the working install before the download had even
started, so a network failure, or the running server's own locked DLLs,
left "whisper.cpp is not installed" behind on a machine where it had
been. The order is now: download, unpack beside, stop the server whose
binary lives there, swap, so the outage is the swap and not the whole
transfer, and a download that fails never takes the server down at all.
A re-downloaded model the server still holds open no longer costs the
finished download; the .part survives and the message says who is holding
the file.

sweep() forgot the pid file before verifying or killing, so one transient
error orphaned a loaded model forever; it verifies, kills, then forgets,
and a verification that could not run leaves the file for the next start.
On Windows the ownership check was the executable's basename, which a
recycled pid could satisfy with somebody else's server; it is the full
image path now, read into a buffer that grows past 260 characters.
stop() takes the launch lock, so stopping during a start kills the server
the start was making rather than missing it, and _forget only removes a
record that is still its own. The relaunch retry stopped reading English
out of the log tail: the retryable failure is a child that exited without
ever listening, and that is what is tested, along with the child still
being alive once its port answers.
