.Dll version check and file install

I have been trying to write a script that will check the version of a particular .dll file and then if the version is not high enough it installs a driver.
The script seems to not check the version properly. Please advise

'On Error Resume Next
Set FS=WScript.CreateObject("Scripting.FileSystemObject")
Set Shell=WScript.CreateObject("WScript.Shell")
DLLFile= "igfxdo.dll"

If FS.FolderExists ("C:\WINNT\System32") Then
  WinDir="C:\WINNT"
Else
  WinDir="C:\WINDOWS"
End If
If FS.FileExists(WinDir&"\System32\”"&DLLFile) Then
  DriverVer = FS.GetFileVersion(WinDir&" \System32\"&DLLFile)
  DriverVerArray=Split(DriverVer,".")
   InstallIt=FALSE
  If UBound(DrVerArray)>=0 And CInt(DrVerArray(0))<6 Then
    InstallIt=TRUE
  Else If UBound(DrVerArray)>=1 And CInt(DrVerArray(1))<14 Then
    InstallIt=TRUE
  Else If UBound(DrVerArray)>=2 And CInt(DrVerArray(2))<10 Then
    InstallIt=TRUE
  Else If UBound(DrVerArray)>=3 And CInt(DrVerArray(3))<5502 Then
    InstallIt=TRUE
 Wscript.Echo "j"
  End If
  If InstallIt Then
    Shell.Run "c:\intel_driver\xp142550.exe",10,TRUE
  End If
  End If
  End If
  End If
  End If
Wscript.Echo "still broke"

Thanks for your help
