This isn't really an issue, but it surprised me, so I thought I would ask about it ...
I normally have my regular programs in "G:\Program Files\". (And used to run LibreOffice Portable from "G:\Program Files\LibreOffice Portable").
I was using an older version of LibreOffice Portable, and set it up on a thumb drive and moved it to that folder and ran it from there - no problems, worked fine.
I upgraded to 3.4.5 and when I tried to over-write the existing file, it told me to select a valid directory, even though I browsed to that one. No problem, I installed it to another folder, deleted the one I had been using and copied the files over. No problem.
Last night, I upgraded to LibreOffice Portable 18.104.22.168 - I again got the message on it not being a valid directory, but this time I didn't want to have to manually re-do all my settings, so I copied the installation to C:\LibreOffice Portable, updated it there and copied it back.
This time, it told me Libreoffice Portable could not launch from this directory as that was for non-portable files.
I moved it to a new folder "G:\Portable Program Files\LibreOffice Portable" and updated my shortcuts to point to it and all is well, but I'm confused on why it cares? I thought the point of a Portable program was that it wouldn't use the registry and could be run from any folder, but apparently not ...
Does anyone know the reason?
