AppCloner 4.2.0 다운로드

Descarga AppCloner.exe y comprueba su SHA256 contra SHA256SUMS.txt. Si no puedes bajar el .exe, usa el zip -python.zip: descomprimelo y haz doble clic en AppCloner.py.
Automatic updates
- The app now installs new versions on its own. It checks on startup,
downloads the new .exe in the background, verifies its SHA256 against the
SHA256SUMS.txt published in the release, and installs it when you close
AppCloner. Nothing is ever swapped underneath you while you are using it.
There is a "Restart now" button if you would rather not wait, and a
Install updates automatically switch in Preferences.
- Why an external helper does the swap. The obvious approach, renaming the
running .exe from inside the program, was measured on Windows 11 and is not
reliable: two identical attempts gave different results, one renaming fine and
the other failing with WinError 32. And in the attempt that did rename, the
old process exited 1 instead of 0 (the control run, untouched, exited 0),
because a PyInstaller onefile executable re-launches itself as a child process
by path. So a short PowerShell helper waits for AppCloner's PID to
disappear, moves the new file over the old one, and relaunches only if asked.
- Nothing is destroyed if it fails. The old executable stays where it is, the
downloaded one stays downloaded, and the helper reopens the app either way. The
outcome is written to a file the app reads on the next start, so a failed update
is reported instead of leaving you thinking you are up to date.
- Nothing is installed that cannot be checked. A download whose hash does not
match the published one is deleted, not kept "just in case". A release with no
SHA256SUMS.txt is refused. To be clear about what this protects: a corrupted
or tampered download in transit, not a compromised GitHub account.
- It refuses where self-updating would be wrong, and says why: from source
(git pull), installed through winget (winget upgrade, so winget keeps its
inventory straight), or installed in Program Files, where the folder is not
writable. Writability is tested by writing a probe file, not guessed from the
path.
- Version comparison now pads to three numbers. Without that, (4, 1) sorts
below (4, 1, 0) and a release tagged v4.1 would have looked newer than the
installed 4.1.0, offering the same update forever.
- New command: appcloner --update checks, downloads and verifies; add --now to
install it as soon as the process exits.

A version that runs without the .exe
- AppCloner.py at the root of the project: double-click it. For anyone whose
browser blocks the executable, whose antivirus deletes it, who gets a
SmartScreen warning about an unsigned binary, or whose network refuses .exe
downloads. It checks the Python version, offers to install the two packages it
needs with pip into your user folder after asking, hides the console before
the window opens, and passes any arguments through.
- Every failure ends in a dialog, never in a console that vanishes. A Traceback
that disappears in a blink tells nobody anything.
- Without pystray there is no tray icon but the app still opens, so a package
that fails to build does not block the launcher.
- Releases now also ship a AppCloner-vX.Y.Z-python.zip with just what you need
to run it that way.

Releasing
- A Release workflow builds, tests, smoke-tests the exe, generates
SHA256SUMS.txt and the Python zip, and opens a draft release when a
vX.Y.Z tag is pushed. It refuses if the tag does not match __version__.
Automatic updates depend on the exe and its checksum coming from the same run;
doing that by hand invites publishing a hash that does not match the binary,
which breaks every user's update at once.
