LibreOffice 4.1.5 crashes to desktop on start (Win 7)

I am trying to install LibreOffice on my machine. This computer has never, ever had any version of LibreOffice or OpenOffice on it.

When I try to run any of the applications, it crashes to desktop within ten seconds, with no error message given. I only get the default Windows “LibreOffice has stopped working” message.

The only advice I have found online has been to reset the user profile, which I tried despite never having installed LO before; naturally, it didn’t help.

Windows 7 Home Basic x64

There is no version 4.5.x. Do you mean 4.2.1?

Sorry, I meant 4.1.5
