Hello hdrider,
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.
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) is availªble here:
http://support.microsoft.com/kb/893803
I'd recommend re-downloading, 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.
I hope this post is helpful, let us know how it works ºut.
