This is effectively a repeat of a FAQ that has elicited no detectable responsive answer. The basic question is: WHAT SHOULD ONE DO NEXT when the 3.5.4 windows installer, running on a win7 machine, first says that one should exit LO 3.5 and the 3.5 quickstarter, when these ARE NOT EVEN INSTALLED on the machine, and are thus certainly not running, and then crashes with the message that the “wizard” was “interrupted”. In the instant case, no other versions of LO are, or ever have been, installed on the machine in question.
Presumably, the “interruption” was caused by the installer itself, which suicidal behaviour is beyond any but the author’s control.
An “answer” saying to uninstall programmes that have never been installed is of no help. The notation that an unanswered question has been “closed” because it is “not a question” is simply baffling.
For those of us who have hit this brick wall - and we seem to be legion - Libreoffice effectively does not exist, since it cannot be installed or used.
