AFAI've understood, LO uninstaller remove some registry keys in HKLM, that
MSOffice application need, but is not able to fix (because of an unprivileged
user).
Solution: run MSOffice application from a PRIVILEGED user, registry keys get
fixed, all works as expected.
For a sake of completeness, i install LO with:
LibreOffice_7.6.4_Win_x86.msi ALLUSERS=1 REBOOT=ReallySuppress
CREATEDESKTOPLINK=0 ISCHECKFORPRODUCTUPDATE=0 REGISTER_NO_MSO_TYPES=1
ADDLOCAL=ALL REMOVE=gm_o_Onlineupdate
Thanks.
