Can't install Vista SP2

[Charles W Davis]

Club member's computer. Windows Vista Home Premium 32-Bit. When I first
picked it up, no shortcut link to a program would work. I drilled down to
the executible files; winword.exe, excel.exe, iexplore.exe and then double
click. The error message went something like this: "This file does not have
a program associated with it from performing this action. Create an
association in the Set Associtation Control Panel." There was no way to
"restore to a previous... No dice. After a post or search, I came across
this page:
http://www.winhelponline.com/articles/105/1/File-association-fixes-for-Windows-Vista.html

With a start up disk, was able to solve that problem.

Disk Cleanup removed 2.45MB. Uninstalled Trend Micro (subscription had
expired a year ago!) Installed and updated AVG 9 Free ran a complete scan -
nothing. I installed Malwarebytes and it found one insignificant cookie. I
went to Windows Update, the first update offered was Service Pack 1. It
installed. I downloaded and attempted to install Service Pack 2. Error
0x8004100a with a link to a web page that offered several means of
installing the service pack; Windows Update -- found a few insignificant
updates, download the SP2 installation file which I had already done, so I
did it again. No dice.

Any suggestions would be appreciated.

DL,

The computer tower is in my office away from the usual devices that require
drivers. It's a Gateway GM54200 desktop. What kinds of drivers should I look
for?

 

[Charles W Davis]

On start up, a message says that a driver was not installed by a Policy. It
is called "WinDriver Virtual Device"

 

[Charles W Davis]

All drivers are up to date...

Ensure an hardware drivers are updated from makers sites or PC maker if
large OEM, eg Dell / HP or Laptop

You would obtain drivers from Gateway specific to your model
Chipset, vid, sound, lan etc

There are many possibilities;
Typically software the emulates a cd/dvd drive might install such a device

A misbehaving driver may well prevent an sp from being installed.
Perhaps a careful examination of Add/Remove might reveal something
