The installer showed "Failed to decompress files" and discarded 7-Zip's
error output, so a failure such as security software quarantining an
extracted file could not be told apart from a full disk or a broken
download.
- InstallerExtract returns negated Win32 errors for launch failures so
they no longer collide with 7-Zip exit codes; 7-Zip writes UTF-8 errors.
- window-frame.dll composes a report (result, archive, destination,
Windows version, full 7-Zip output), saves it under the updater cache
directory, and presents a task dialog with the first error line, a
collapsible bounded excerpt, and a Copy error details button. Silent
installs keep only the report; a missing task dialog falls back to a
message box.
- Unsigned Windows builds name their installer *-unsigned.exe so a
shared file cannot pass for a release artifact; version discovery
still counts them.
- The directory smoke asserts the saved report on a broken archive and
smoke-windows.ps1 accepts the prepared DLL.
Refs #4893
Product dropped Harness-home cleanup from the uninstaller, so the opt-in page,
its bilingual dialog, the uninstall.ini home record and the overlap check go
away. The uninstaller now always removes the Electron user-data directory,
the %APPDATA% product directory and the updater cache through the native
helper; the Harness home is never touched. Silent uninstalls remove the same
data, upgrades retain it, and a locked file is logged instead of stopping the
uninstall.
Electron derives user data from the scoped package name, so the removal
targets %APPDATA%\@deepseek-ai\dsh-desktop and removes the empty scope
directory afterwards. The previous fixture used an unscoped name and never
reached that directory; the fixture now uses a scoped package name.
The native uninstall smoke runs end to end on the development host after two
test fixes: the interactive uninstaller was launched hidden, which made every
control invisible to the text search, and the Chinese finish text matched
"已经从" instead of MUI's "已从你". The native remover regression is renamed
data-cleanup-test.exe because UAC installer detection demanded elevation from
the unmanifested uninstall-data-test.exe.
The Windows uninstaller keeps every user file by default and adds a custom
page with unchecked options for desktop browser data and update caches, the
desktop plugin profile, and the complete Harness home. Selecting the whole
home requires a native warning that names the actual folder and the CLI
impact, defaults to Cancel, and forces the desktop child selection. Silent
and upgrade uninstalls never remove data, including through the legacy
--delete-app-data flag, which the adapted upstream template no longer honors.
Packaged Desktop records its resolved home in uninstall.ini under the
Electron user-data directory so a custom DSH_HOME is offered instead of the
default; a length field detects truncated NSIS reads and an invalid record
disables whole-home removal. The native remover in window-frame.dll rejects
protected roots and overlap with retained data, holds directory handles
during traversal, and unlinks reparse points without entering their targets.
Installation now also writes InstallLocation on the Windows uninstall entry,
which Explorer needs to associate the Start menu shortcut with this entry so
that the context-menu Uninstall launches the uninstaller directly instead of
opening the installed-apps list. The upstream template only records the
value under its private key.
