MS: Script Get List .NET Framework version for list of computers

One of my colleague in the WIndows Operations team asked me to create a VBscript to get all .NET Framework Version installed on a list of servers (provided in a .txt file). I created the script using blocks so the team can reuse it for multiples tasks.

To use the script: Cscript NetFramework.vbs , where is the text file with a list of servers or machines.

Version(2) = "2.0"
NetF(3) = "Software\Microsoft\NET Framework Setup\NDP\v3.0"
Version(3) = "3.0"
NetF(4) = "Software\Microsoft\NET Framework Setup\NDP\v3.5"
Version(4) = "3.5"
NetF(5) = "SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Client"
Version(5) = "4.0"
NetCount = 5

Set objArgs = WScript.Arguments
if objArgs.Count = 0 then
WScript.Echo "Command line parameters not specified"
WScript.Echo "Usage: Cscript NetFramework.vbs "
WScript.quit
end if
ServerList = trim(objArgs(0))
OutputFile = "NetF-Report.csv"
