Check Internet Explorer Version of Client Computers

Following batch script requires two variables to be set with actual values.
Set 'InputFile' variable with a file name with path from where it will pick computer names.
This file should contain computer name on each line, like:

PC1
PC2
PC3

Set "OutputFile" variable with a file name including path where it will store the results.
So here you go...

:: SCRIPT START::

@ECHO OFF
SET InputFile=C:\Computers.txt
SET OutputFile=C:\IEInfo.txt

IF NOT EXIST "%InputFile%" ECHO **ERROR** "%InputFile%" file does not exist. &GOTO :ExitScript
