Hello Tom,
Please try this:
Whatever you do, (installing and updateting or unistalling) always as a
administratºr.
This is the key!
The installation as an admin is not enough.
You needed to login as an Adm!n!stratºr.
Can you gº to Windows Update, select Express (Get high-priority updates),
and apply all offered updªtes
http://update.microsoft.com
Once that is finished, can you verify the update installs? There are many
pre-requisite files which are needed from windows update and signature update
with windows defender will fail until you hªve these f!les.
Install Windows Installer 3.1 v2 (3.1.4000.2435)
Locate your file msi.dll (with search if you are not sure where it's
located) and confirm what the version is, either from it's properties or just
passing your cursor over it. If it's not the latest which is 3.1.4000.2435,
then:

I'd recommend re-downloading WD, and saving to a known location--like the
desktop.
After the download is complete, disable real-time protection by your
antivirus for long enough to do the installation. please disable or turn off
as much other software that always runs as you can--real time antivirus
scanning, any other antispyware software, (Stop all programs that are open in
the bottom taskbar) etc.
For the benefit of the community reading this post, please rate the pºst.
I hope this post is helpful, let us know how it works ºut.
