Description MK 2026-01-29 15:11:46 UTC
Description:
When updating LibreOffice, the entire installation process runs very quickly, and after completion, none of the installation components are available. The Program Files directory does not contain the usual content, and the folder is empty. Therefore, it is not possible to run any LibreOffice application. This has happened on two out of 10 computers where I installed the update. Repeatedly running the installation does not help.

Translated with DeepL.com (free version)

Actual Results:
After starting the installation of LibreOffice_25.8.4_Win_x86-64.msi, the entire process runs very quickly.

Expected Results:
After end of installation there are no files in the Program Files folder and the individual applications are not available. There are no LibreOffice application icons in the Windows menu either.


Reproducible: Always


User Profile Reset: No

Additional Info:
This behavior has occurred on two out of 10 computers where I have installed the update so far. All of them have the same OS version, Windows 11 25H2. I did not reset the user profile because it was not possible due to the user's workload.

I tried to attach the installation log, but I was unable to do so.

From where you download the installation file?

Have you tried to reinstall?

Is the installation down as administrator?
Comment 3 MK 2026-01-31 09:00:57 UTC
I always download the installation file exclusively from the official LibreOffice repository - https://www.libreoffice.org/donate/dl/win-x86_64/25.8.4/cs/LibreOffice_25.8.4_Win_x86-64.msi

Yes, I tried to run the installation repeatedly, and LibreOffice did not install. That's the strangest thing.

The installation was run as a regular user who was then asked for administrator privileges after starting the installation.

I am attaching the installation log, which I have now managed to upload.

I understand. I will try to disable Windows Defender before installation. However, during previous installation attempts, Defender did not display any warning windows.
Comment 7 m_a_riosv 2026-01-31 22:48:30 UTC
Not only at installation, try before running LibreOffice, I have seen that sometimes, gives permissions to soffice.exe folder (C:\Program Files\LibreOffice\program)  in defender, solves the issue.
