Windows Installer error when installing Windows Media Encoder
"I need to install Windows Media Encoder 9 Series" on a laptop (Lenovoi X60 running XP Pro SP3). This isn't usually a problem but on this particular one I keep receiving the following error message:
I can't seem to find a solution to this anywhere :(
The Windows Installer service cannot update one or more protected Windows files.
To date I have:
* Re-installed Windows Installer (version 4.5)
* Re-installed SP3
* Tried installing from the WMEncoder.exe and the WMEncoder.msi (extracted from within)
* Re-downloading the file (although it does work on other machines)
* Crossing my fingers as I press 'Install'!
The typically cryptic message from the Application Log is:
Product: Windows Media Encoder 9 Series -- Error 1933. The Windows Installer service cannot update one or more protected Windows files. SFP Error: -536870654. List of protected files:\r\nc:\windows\system32\wmerror.dll
