            Bug ID: 145304
           Summary: LibreOffice 7.1.6.2 crashes immediately on Windows 7
                    no matter which GUI module I'm trying to launch
           Product: LibreOffice
           Version: 7.1.6.2 release
          Hardware: x86-64 (AMD64)
                OS: Windows (All)
            Status: UNCONFIRMED
          Severity: normal
          Priority: medium
         Component: LibreOffice
          Assignee: libreoffice-bugs@lists.freedesktop.org
          Reporter: idw....@t-online.de

Description:
I've updated LibreOffice last night on both my Windows 10 and Window 7 machines
(both 64bit). While the former launches w/o issues the latter crashes
immediately while launching any of its GUI components without showing any of
its UI. What it does successfully is "soffice.exe --convert-to pdf some.htm",
but it also crashes on "soffice.exe --convert-to rtf some.htm". The post mortem
crash dump provided by WinDbg reports exception code 0xC000001D (Illegal
instruction) with the following call stack (created when launching soffice.exe
as you can certainly tell from it):

The final assembly line reads:
vmovups ymm0,xmmword ptr [rcx] ds:00000000`00b6f300

Steps to Reproduce:
No steps required, just launch the application "as is".

Actual Results:
Can't use LibreOffice.

Expected Results:
You get the picture ...


Reproducible: Always


User Profile Reset: Yes


OpenGL enabled: Yes

Additional Info:
I even did a reboot after installation just to be sure there wouldn't be any
leftovers from uninstalling the previous version or any other application
interfering. Setup ran w/o issues. German helpfiles installed after completion
w/o issues either. Previous version didn't crash.

Can't copy anything from the "Help - About" screen for obvious reasons ...

Disabling the user profile doesn't change anything

libreoffice --safe-mode crashes
