Libreoffice 5.1.1.3 on Windows 7

From where did you download LO?; if not from there actual site, then
the version may be corrupt -
          suggestion: go to the LO site & re-download allowing this one to
take over the LO you presently have on your machine,

       Hoping this helps,

My LO installation is from the main LO website and I used the same LO
installation file on both machines.

I am convinced that there is a problem on my machine and I am trying to
locate that problem.
