locate .exe on remote PC

I need to query our network and determine which machines have certain apps installed.

I was hoping to have powershell read from a CSV with netbios names and output a list of PCs that have the exe on them.

What would a script like that look like?

Do you know where the exe file will be? Searching an entire file system is quite time-consuming, even if we went down the remoting road and had the client system do it for you.

hope you don't mind it's vbs.

the script ping first to check availability, then query installed apps on registry and log each program for each machine if installed or not.

it reads he machine list from a file (c:\temp\machines.txt)
the apps list are hardcoded but can be also read from a file.

i was checking 2 applications Safari & Windows Live Essentials, so the output log should be something like this.


[meirpc]
Safari could not be found
Windows Live Essentials could not be found

[s004]
Safari could not be found
Windows Live Essentials could not be found

[s001]
Safari could not be found
Windows Live Essentials could not be found

[s002] is unavailable

[s003] is unavailable

[rana]
Safari could not be found
Windows Live Essentials was found

[markg]
Safari could not be found
Windows Live Essentials could not be found

[ilyak2]
Safari could not be found
Windows Live Essentials was found

const APPS_LIST = "Safari,Windows Live Essentials"
const MACHINES_LIST_FILE = "c:\temp\machines.txt"

set objFSO = createobject("scripting.filesystemobject")
set objFile = objFSO.OpenTextFile(MACHINES_LIST_FILE, 1)
arrMachines = Split(objFile.ReadAll, vbNewLine)
objFile.Close

Set objTextFile = objFSO.OpenTextFile ("c:\temp\apps.log", 2, True)

for each strComputer in arrMachines
	if Trim(strComputer) <> "" then
		objTextFile.WriteLine
		if Ping(strComputer) = false then
			objTextFile.WriteLine "[" & strComputer & "]" & " is unavailable"
		else
			On error resume next
			
			arrIA = getApps(strComputer)

			objTextFile.WriteLine "[" & strComputer & "]"

			If IsArray(arrIA) Then
				For Each prog In Split(APPS_LIST, ",")
					found=false
					For Each strApp In arrIA
						if InStr(Trim(strApp), Trim(prog)) > 0 then
							found=true
							exit for
						end if
					next
					
					if found = false then
						objTextFile.WriteLine prog & " could not be found"
					else
						objTextFile.WriteLine prog & " was found"
					end if
				Next
				
			Else
				objTextFile.WriteLine "[" & strComputer & "] is unavailable" 
			End If
		end if
	end if
Next 

objTextFile.Close

wscript.echo "done"


Function Ping(strHost)

    dim objPing, objRetStatus

    set objPing = GetObject("winmgmts:{impersonationLevel=impersonate}").ExecQuery _
      ("select * from Win32_PingStatus where address = '" & strHost & "'")

    for each objRetStatus in objPing
        if IsNull(objRetStatus.StatusCode) or objRetStatus.StatusCode<>0 then
			Ping = False
        else
            Ping = True
        end if
    next
End Function 

Function getApps(strComputer)
	HKLM = &H80000002 'HKEY_LOCAL_MACHINE
	strKey = "SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\"
	Set objReg = GetObject("winmgmts:{impersonationLevel=impersonate}//" & strComputer & "/root/default:StdRegProv")

	If Err.Number > 0 Then
		getApps = False
		Err.Clear
		Exit Function
	End If

	objReg.EnumKey HKLM, strKey, arrSubkeys

	arrInstalledApps = Array()

	For Each strSubkey In arrSubkeys

		intRet1 = objReg.GetStringValue(HKLM, strKey & strSubkey, "DisplayName", strValue1)
		If intRet1 <> 0 Then
			objReg.GetStringValue HKLM, strKey & strSubkey, "QuietDisplayName", strValue1
		End If

		If InStr(strValue1, "Hotfix") Or InStr(strValue1, "Security Update") Or InStr(strValue1, "Update for Windows") Then
			'nothing
		Elseif strValue1 <> "" Then
			ReDim Preserve arrInstalledApps(UBound(arrInstalledApps) + 1)
			arrInstalledApps(UBound(arrInstalledApps)) = strValue1

	getApps = arrInstalledApps
End Function
