64-bit Windows registry and WiseScript Package Editor

Can someone explain this to me? I'm seeing different behavior on two similar PCs depending on whether I run a VBScript or run that same script within a Wise-created EXE.

My PC is Windows XP Professional x64 Edition, Version 2003, Service Pack 2.
I'm trying to read the "Install" value (a dword value) for registry key
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1. This key exists both on my PC and a test PC, which is also XP Pro 64 bit, etc.

This is the VBScript I'm using:
Const HKEY_CURRENT_USER = &H80000001 Const HKEY_LOCAL_MACHINE = &H80000002 strComputer = "." Set oReg=GetObject("winmgmts:{impersonationLevel=impersonate}!\\" &_ strComputer & "\root\default:StdRegProv") strKeyPath = "SOFTWARE\Microsoft\PowerShell\1" strValueName = "Install" oReg.GetDWORDValue HKEY_LOCAL_MACHINE,strKeyPath,strValueName,dwValue MsgBox "Install value is: " & dwValue

Don't have error handling built in yet because I'm still testing.

This script reports back the value of "Install" correctly both on my PC and the test PC. So far so good.

Next I wrote a Wise package (using Wise Package Studio 8) with the WiseScript Package Editor. It copies the VBScript locally and then runs it. Here's the Wise code:
item: Set Variable Variable=C Value=C: end item: Install File Source=.\MSI\script\dword.vbs Destination=%C%\test\dword.vbs Flags=0000000010100010 end item: Execute Program Pathname=%C%\test\dword.vbs Flags=00000010 end

I compile in Wise to an EXE and then run it. On my PC the message box shows me the correct value for "Install", which is "1." But on my test PC, it doesn't report back any value at all. So I'm not sure why the VBScript behaves correctly on both PCs, but calling the VBScript via a Wise-created EXE results in my PC reporting correctly and the other not. I've tested against a third 64 bit XP machine, also, just to make sure my results weren't a fluke.

What I'm trying to do specifically is check if PowerShell is installed on a PC. I realize that for this particular example I can also check if the directory exists in Wise, but for my particular task at hand, there will be instances when I have to check the registry, and right now I know of no reliable way to do it when my target PC is 64 bit.
