Bug ID: 173024
Summary: Automatic update to LibreOffice 26.2 repeatedly
restarts after failure, leaving a persistent update
state and installing a crashing version
Product: LibreOffice
Version: 26.2.5.2 release
Hardware: All
OS: Windows (All)
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: LibreOffice
Assignee: [email protected]
Reporter: [email protected]
Description:
I encountered the following reproducible sequence on Windows 10 Pro (22H2,
build 19045.7548).
Initial situation
LibreOffice 25.8.3.2 x64 installed and working correctly.
During startup, LibreOffice proposed an update to 26.2.
I accepted the update.
The update completed without displaying any error message.
After that, LibreOffice no longer started.
Symptoms
soffice.exe starts soffice.bin.
soffice.bin terminates almost immediately.
Windows Event Viewer reports:
APPCRASH
faulting module: MSVCP140.dll
Process Monitor shows the process exiting with status:
0xC0000142 (STATUS_DLL_INIT_FAILED)
Investigation
I verified:
Visual C++ Redistributable repaired.
sfc /scannow completed successfully.
DISM /Online /Cleanup-Image /RestoreHealth completed successfully.
Malwarebytes disabled (no change).
Fresh LibreOffice user profile (no change).
None of these changed the behaviour.
Important observation
After completely removing LibreOffice (including cleaning the MSI registration
using Microsoft's Program Install and Uninstall Troubleshooter) and
reinstalling LibreOffice 25.8.3.2:
soffice.bin was correctly version 25.8.3.2.
Writer started successfully.
However, immediately after startup:
a web page saying "You have updated to LibreOffice 26.2" opened,
LibreOffice launched updater.exe,
Windows displayed a UAC prompt requesting elevation.
The command line shown by the UAC dialog contained:
...\updater.exe
"C:\Users\<user>\AppData\Roaming\LibreOffice\4\updates\0"
"C:\Program Files\LibreOffice"
...
If I refused elevation:
Writer 25.8.3.2 continued to run normally.
Every subsequent launch repeated exactly the same behaviour.
Workaround
I renamed:
%APPDATA%\LibreOffice\4\updates
to
updates_old
After doing so:
the updater was no longer launched,
no UAC prompt appeared,
LibreOffice 25.8.3.2 worked normally.
Expected behaviour
If a previous update failed, LibreOffice should either:
discard the stale update state,
or inform the user and offer to retry,
but it should not repeatedly relaunch the updater on every startup.
It also appears that the failed update left LibreOffice in a state where
version 26.2 consistently crashed on startup.
