I need to write VBS WScript.Echo output to text or cvs

Question

I am attempting to write a VBScript that will list all of the installed application on a system in a text file or csv. I was able to find an existing code to list all of the software (including name, version, date, and size). When I currently run it as I have found it the echo comes up as a host echo pop up. What do I need to add to the vbs to make it output each of the echos to a File? I am sure this is easy, but i can't seem to find a solution.

Below is the script I found:

Dim fso
Set fso = WScript.CreateObject("Scripting.Filesystemobject")
' List All Installed Software





Const HKLM = &H80000002 'HKEY_LOCAL_MACHINE
strComputer = "."
strKey = "SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\"
strEntry1a = "DisplayName"
strEntry1b = "QuietDisplayName"
strEntry2 = "InstallDate"
strEntry3 = "VersionMajor"
strEntry4 = "VersionMinor"
strEntry5 = "EstimatedSize"

Set objReg = GetObject("winmgmts://" & strComputer & _
 "/root/default:StdRegProv")
objReg.EnumKey HKLM, strKey, arrSubkeys
WScript.Echo "Installed Applications" & VbCrLf
For Each strSubkey In arrSubkeys
  intRet1 = objReg.GetStringValue(HKLM, strKey & strSubkey, _
   strEntry1a, strValue1)
  If intRet1 <> 0 Then
    objReg.GetStringValue HKLM, strKey & strSubkey, _
     strEntry1b, strValue1
  End If
  If strValue1 <> "" Then
    WScript.Echo VbCrLf & "Display Name: " & strValue1
  End If
  objReg.GetStringValue HKLM, strKey & strSubkey, _
   strEntry2, strValue2
  If strValue2 <> "" Then
    WScript.Echo "Install Date: " & strValue2
  End If
  objReg.GetDWORDValue HKLM, strKey & strSubkey, _
   strEntry3, intValue3
  objReg.GetDWORDValue HKLM, strKey & strSubkey, _
   strEntry4, intValue4
  If intValue3 <> "" Then
     WScript.Echo "Version: " & intValue3 & "." & intValue4
  End If
  objReg.GetDWORDValue HKLM, strKey & strSubkey, _
   strEntry5, intValue5
  If intValue5 <> "" Then
    WScript.Echo "Estimated Size: " & Round(intValue5/1024, 3) & " megabytes"
  End If
Next

One way to go about this would be to run the script via cscript.exe and redirect the output to a file:

cscript.exe //NoLogo "C:\path\to\your.vbs" >"C:\output.txt"

If you want to modify the script to write its output to a file regardless of how it's run, you need to add code for opening/closing the output file:

Dim fso
Set fso = WScript.CreateObject("Scripting.Filesystemobject")
Set f = fso.OpenTextFile("C:\output.txt", 2)

...

f.Close
'End of Script

and replace each occurrence of WScript.Echo with f.WriteLine.

Skarykid - I know you received and answer to this almost 6 months ago, but I've been looking for a similar script & haven't had much success getting exactly what I wanted. I've modified the script you provided, added Ansgar's suggestions & a little code of my own to come up with the following souped-up version.

This script will generate a tabulated text file of all 32bit and 64bit applications installed on the local machine & will then open the resulting file in notepad.

Hope this helps you or anyone else coming across this thread.

'listapps.vbs
'Generates a text file listing all 32bit & 64bit apps installed on the local machine
'===================================================================================

'Declare constants, variables and arrays
'---------------------------------------

'Registry keys and values
Const HKLM = &H80000002 'HKEY_LOCAL_MACHINE 

Dim arrKeys(1)
arrKeys(0) = "SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\"
arrKeys(1) = "SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall\"

strComputer = "." 
strEntry1a = "DisplayName" 
strEntry1b = "QuietDisplayName" 
strEntry2 = "Publisher"
strEntry3 = "InstallDate"
strEntry4 = "EstimatedSize"
strEntry5 = "DisplayVersion"

'Create the output file
Dim objShell, objShellEnv, strComputerName, objFso
Set objShell = WScript.CreateObject("WScript.Shell")
Set objShellEnv = objShell.Environment("Process")
strComputerName = objShellEnv("ComputerName")
Set objFso = WScript.CreateObject("Scripting.FileSystemObject")
Set outputFile = objFso.CreateTextFile(strComputerName & ".txt", True)
'===================================================================================

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

'Print header (comment out the line below if you do not want headers in your output file)
'outputFile.WriteLine"Name" & vbTab & "Publisher" & vbTab & "Installed On" & vbTab & "Size" & vbTab & "Version" & VbCrLf 

For i = 0 to 1

  'Check to ensure registry key exists
  intCheckKey = objReg.EnumKey(HKLM, arrKeys(i), arrSubkeys)

  If intCheckKey = 0 Then
    For Each strSubkey In arrSubkeys 
      intReturn = objReg.GetStringValue(HKLM, arrKeys(i) & strSubkey, strEntry1a, strValue1) 

      If intReturn <> 0 Then 
        objReg.GetStringValue HKLM, arrKeys(i) & strSubkey, strEntry1b, strValue1 
      End If 

      objReg.GetStringValue HKLM, arrKeys(i) & strSubkey, strEntry2, strValue2
      objReg.GetStringValue HKLM, arrKeys(i) & strSubkey, strEntry3, strValue3
      objReg.GetDWORDValue HKLM, arrKeys(i) & strSubkey, strEntry4, strValue4
      objReg.GetStringValue HKLM, arrKeys(i) & strSubkey, strEntry5, strValue5

    If strValue1 <> "" Then
      outputFile.WriteLine strValue1 & vbTab & strValue2 & vbTab & strValue3 & vbTab & strValue4 & vbTab & strValue5
    End If

    Next 

  End If

Next 

'Close the output file
outputFile.Close

'Launch output file for review
objShell.run "notepad.exe " & strComputerName & ".txt"

'Clean up and exit
Set objShell = Nothing
Set objFso = Nothing

In addition to Ansgar's top-rated answer, changing

Set f = fso.OpenTextFile("C:\output.txt", 2)

to

Set f = fso.CreateTextFile("C:\output.txt", 2)

allows VBS script to create the output files rather than requiring an existing blank file to already be in the destination.
