libreoffice installation could not be completed

On a PC with Windows 7 Home 64 bit, I have installed LibreOffice.
Then, I have disinstalled it.
Then, I have tried to reinstall it, but I could not.
The error message was that “libreoffice user installation could not be completed”.
I have tried to install different versions of LibreOffice, but the result was the same.
What could I do?
What is there that prevent the installation from being completed?
Many thanks for your help!
