I have tested both on Windows 10 and 11 on two different computers both with 64-bit OS. All "direct" LibreOffice apps don't start with Portable Apps version of LibreOffice 18.104.22.168.
I have tried with different install paths with new clean installation and it does not work no matter how I have changed the install path. The path C:\PortableApps\LibreOfficePortable22.214.171.124\ was for example used.
It's the same behavior when starting from within the portableapps.com launcher as directly from installed path using windows explorer.
