I can’t install LibreOffice?
Error message 1317 while attempting to create the directory c:/Program File\LibreOffice\share
Did you already look for related reports? See error 1317 at DuckDuckGo.
It isn’t a LibreOffice error but should be related to missing rights on the system level.
As it occurs when trying to write to C:\Program Files, you may probably need but miss Admin rights. What Windows version?
