Can't write a file in Win7

[Docfxit]

I'm having trouble unzipping a file in Win7 64bit

My first problem is trying to figure out the error that is happening.

The code I am using is:

Opt("WinWaitDelay",100)
Opt("WinTitleMatchMode",4)
Opt("WinDetectHiddenText",1)
Opt("MouseCoordMode",0)
Opt("SendKeyDelay", 5)
AutoItSetOption("TrayIconDebug", 1) ;0-off
; Set so that tray displays current line number

; Include User.INI Info
#include "IniRead.au3"
$Var1 = "C:\Dnload\9xAddons\Ultimate Windows Tweaker v 2.1.zip"
If _OSVersion() = "Win7" Or "Win7X64" Then
    $ProgramFiles = "C:\Programs\"
    $Win7 = "7"
Else
    $ProgramFiles = "C:\Program Files\"
EndIf
Local $sUserName = "Administrator"
Local $sPassword = ""
$Return = RunAsWait($sUserName, @ComputerName, $sPassword, 0,@Comspec & ' /c C:\Dnload\9xAddons\UnZip.bat "' & $Var1 & '" & "' & $Win7 & '"')
If @error Then
    MsgBox(0, "Error unzipping file", "Error code: " & @error & @CRLF & $Var1 & @CRLF & "Return value = " & $Return)
Else
    MsgBox(0, "File UnZipped", "File UnZipped Correctly")
EndIf

The error I get is:

I'm getting an error code of 1

That means it failed. How can I figure out why? The Return value = 0

Thanks,
