Question: I need to read the location of the Temporary ASP.NET Files folder from VBScript as part of a post-installation task in an installer created using a Visual Studio 2008 deployment project.

I thought I would do something like this:

```
Set oShell = CreateObject("Wscript.Shell")
strPath = oShell.RegRead("HKLM\SOFTWARE\Microsoft\ASP.NET\2.0.50727.0\Path")

```

and then concatenate strPath with "\Temporary ASP.NET Files" and be done with it.

On an x64 system, however, I am getting the value from the WOW6432Node (HKLM\SOFTWARE\Wow6432Node\Microsoft\ASP.NET\2.0.50727.0), which gives me the 32-bit framework path (C:\Windows\Microsoft.NET\Framework\v2.0.50727), but on an x64 system, I actually want the 64-bit path, i.e. C:\Windows\Microsoft.NET\Framework64\v2.0.50727.

I understand that this happens because the .vbs file is run using the 32-bit script host due to the parent process (the installer) being 32-bit itself.

How can I run the script using the 64-bit script host - or - how can I read the 64-bit values even if the script is run using the 32-bit script host?

Answer: 
Not sure about launching the 64-bit script host version, but you should be able to access the 64-bit registry from the 32-bit script host using the WMI [`StdRegProv`](http://msdn.microsoft.com/en-us/library/aa393664(VS.85).aspx) class, like this:

```
Const HKEY_LOCAL_MACHINE = &H80000002
sPath = ReadRegStr (HKEY_LOCAL_MACHINE, "SOFTWARE\Microsoft\ASP.NET\2.0.50727.0", "Path", 64)
WScript.Echo sPath

' Reads a REG_SZ value from the local computer's registry using WMI.
' Parameters:
'   RootKey - The registry hive (see http://msdn.microsoft.com/en-us/library/aa390788(VS.85).aspx for a list of possible values).
'   Key - The key that contains the desired value.
'   Value - The value that you want to get.
'   RegType - The registry bitness: 32 or 64.
'
Function ReadRegStr (RootKey, Key, Value, RegType)
    Dim oCtx, oLocator, oReg, oInParams, oOutParams

    Set oCtx = CreateObject("WbemScripting.SWbemNamedValueSet")
    oCtx.Add "__ProviderArchitecture", RegType

    Set oLocator = CreateObject("Wbemscripting.SWbemLocator")
    Set oReg = oLocator.ConnectServer("", "root\default", "", "", , , , oCtx).Get("StdRegProv")

    Set oInParams = oReg.Methods_("GetStringValue").InParameters
    oInParams.hDefKey = RootKey
    oInParams.sSubKeyName = Key
    oInParams.sValueName = Value

    Set oOutParams = oReg.ExecMethod_("GetStringValue", oInParams, , oCtx)

    ReadRegStr = oOutParams.sValue
End Function

```

*NB: I'm under a 32-bit OS right now, so can't verify that this example works. Beware of bugs :-)*
