VBScript列出Windows Server 2008 R2上已安装的软件

Question

I want to list the installed softwares on windows server 2008 R2 with a VBscript. I want to verify prerequisite softwares (one of them is .NET Framework 3.5.1). I actually have two solutions and they both doesn't show all the softwares.

Const HKLM = &H80000002 'HKEY_LOCAL_MACHINE
installedSoftwaresPath = "SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\"

Set objReg = GetObject("winmgmts://./root/default:StdRegProv")

objReg.EnumKey HKLM, installedSoftwaresPath, arrSubkeys
For Each strSubkey In arrSubkeys
    Ret = objReg.GetStringValue(HKLM, installedSoftwaresPath & strSubkey, "DisplayName", SoftwareName)
    If Ret <> 0 Then
    objReg.GetStringValue HKLM, strKey & strSubkey, "QuietDisplayName", SoftwareName       
    End If
    If SoftwareName<> "" Then
        WScript.Echo VbCrLf & "Display Name: " & SoftwareName
    End If
Next

The other solution is this one :

Set objWMIService = GetObject("winmgmts:" & "{impersonationLevel=impersonate}!\\.\root\cimv2")
Set colSoftware = objWMIService.ExecQuery("Select * from Win32_Product")

For Each objSoftware in colSoftware
    WScript.Echo objSoftware.Caption
Next

Is it possible to get ALL the installed softwares? if not I'm gonna make a specific solution for every prerequisite softwares.

EDIT : Some software found by my scripts :

Microsoft Application Error Reporting, Microsoft Visual C++ 2008 Redistributable, Microsoft Security Client, Adobe Reader

What I want to found : .NET framework 3.5.1

I want a generic solution to found every softwares installed.

SOLUTION : It seems that there is no generic way to check for installed software. I've found the .NET framework registry key in this path :

"SOFTWARE\Microsoft\MSBuild\ToolsVersion\v3.5\"

Answer 1

Without having access to your server to see how the software you're looking for is installed, I can only guess at how you might modify your script.

However, there are other places you should probably be looking besides: HKLM\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Uninstall\\

For example, you may want to look in:

HKLM\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall
HKLM\SOFTWARE\Classes\Installer
HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Installer\UserData

It's possible that you will find what you are looking for in one of those locations.

You may also want to use RegEdit to do a "Find" for ".NET Framework 3.5.1" to see if that shows up somewhere that you can reliably find it.
