Here is the workaround that worked for me

(and its hilarious)

1 Open a Command box !!AS ADMINISTRATOR!! (type cmd and right click-choose run as administrator)

2 Go to windows/installer directory by typing

cd \windows\installer

and you'll be in the installer dir ( see C:\Windows\Installer> before prompt)

3 Locate the msi you want installed or uninstalled and type name of that msi.

The msi now works properly.

On my new Windows 8 machine I have had lots of problems with these errors - few of the fixes suggested worked consistently but the steps below have worked every time for me.

1. Firstly I am running a Windows 7 desktop setup to get away from the Metro interface
2. From the Start option, find the shortcut to the cmd.exe program, right click on it and make sure to open it using the 'Run as Administrator' option
3. Depending on your User Account Control settings you may have to respond OK to the question as to whether to Allow changes to the PC.
4. Proceeding should open a black window with some text in it something like this

                                                 C:\Windows\system32>

5. Type in the path to the .msi file causing the problem and press return e.g. if the .msi is located in the C:Temp folder then you need to type C:\Temp\WhateverTheProgramNameIs.msi
6. The install should then proceed correctly.

THREE WORDS: I LOVE YOU :)

YOU SAVED ME COUNTLESS WORK HOURS, AND I LOVE YOU.

I HOPE EVERYONE APPRICIATE WHAT YOU JUST DID HERE.

MILLION THANKS, AND I WISH I CAN REWARD YOU SOMEHOW
