            Bug ID: 166116
           Summary: LibreOffice Writer and Calc fail to launch directly
                    with non-admin user: "You do not have sufficient
                    privileges to access this file or function
           Product: LibreOffice
           Version: 24.8.6.2 release
          Hardware: x86-64 (AMD64)
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: LibreOffice
          Assignee: [email protected]
          Reporter: [email protected]

Description:
After a clean installation of LibreOffice on a freshly reinstalled and fully
updated Windows 11 system, the swriter.exe and scalc.exe executables cannot be
started by a regular (local administrator) user. Attempting to start Writer or
Calc directly results in the following error message:

"You do not have sufficient privileges to access this file or function."

Oddly, launching soffice.exe with administrative rights and starting
Writer/Calc from within the LibreOffice hub works without any issues. Starting
swriter.exe directly (without elevation) fails every time.

This issue began occurring after a system previously had CCleaner and EaseUS
software installed. However, even after completely reinstalling Windows,
removing all traces of those apps, resetting permissions, and reinstalling
LibreOffice as Administrator via msiexec /i, the issue persists.

Steps to Reproduce:
1.On a clean Windows 11 system, install LibreOffice (any recent version) using
the .msi installer via msiexec /i with admin rights

2. Attempt to launch C:\Program Files\LibreOffice\program\swriter.exe as a
regular user (local administrator account)

3. Alternatively, double-click a .odt file to trigger swriter.exe



Actual Results:
Only launching soffice.exe as Administrator and using the built-in UI to start
Writer/Calc works.

Expected Results:
LibreOffice Writer and Calc should launch normally when started directly,
without requiring administrative privileges, as they have always done before.


Reproducible: Always


User Profile Reset: No

Additional Info:
Problem occurs even after a complete Windows reinstall

New user accounts also experience the same issue

Process Monitor shows no access denial or missing files, only abnormal
termination of swriter.exe when run non-elevated

swriter.exe works when copied to a different location and run as Administrator

Enabling/disabling Skia had no effect

All Defender/Controlled Folder Access features were disabled

No AppLocker, SRP or WDAC rules were configured

The problem appears to relate to a system-level execution restriction tied to
swriter.exe specifically
