Upgrade to 4.2.2

I have LO 4.3.2 installed on my laptop computer (Win7 Pro 64-bit). After I’d installed it, I deleted the installation msi file.
When I try to run the installer for 4.4.2, it asks for my 4.3.2 msi file which I no longer have. I’m assuming 4.4.2 is uninstalling 4.3.2 before it installs itself. But since it asks for my 4.3.2 msi file and I don’t have it, it won’t finish the installation. What it does do, however, is uninstall at least parts of 4.3.2 as I can no longer run Writer or Calc.
So I’m left with a screwed up 4.3.2 installation and I can’t install 4.4.2.
What am I supposed to do?

Download the 4.3.2 version from Index of /libreoffice/old
and place it where is was before.
