[Closed] LibreOffice Portable 5.4.0 failed to start

[Duplicate of thread: https://portableapps.com/node/56647 ]

windows 7 Ultimate 32bit
LibreOffice version 5.4.0 was installed over previous v5.3.4
None of Office Apps can be launched .... cursor spins for a sec & dies like nothing eve happened
No error messages / no events logged
Reinstalling previous v5.3.4 over the new not working 5.4.0 one brings Office back alive
Thanks
