Input Error: There is no script engine for file extension “.vbs”.

VBScript support (Windows Scripting Host, as far as I understand) seems to be been broken on my system (for example, when I run a Microsoft FixIt tool it doesn't work and complains that "There is no script engine for file extension .vbs."). I've found Windows Script 5.7 for Windows XP but it refuses to install saying I have a newer service pack already installed. How to repair VBScript then?

Try to repair the WMI. Do this:

Open a command promt (cmd) and run the following commands, one by one.

rundll32 wbemupgd, UpgradeRepository
cd /d %windir%\system32\wbem
for %i in (*.dll) do RegSvr32 -s %i
for %i in (*.exe) do %i /RegServer

Reboot computer.
