vbscript opens a clickonce app needs to wait until running

I have a script that opens a vb.net clickonce app.  I need the script to wait until the app is updated and running before doing anything,  Now I have a wait in there but depending on a users machine, my delay is either too long or too short.  I would like to be able to check processes running.  Anyone else doing this?  Code Below.
So instead of "autECLSession.autECLPS.Wait 1300" I want something like wait till myApp.exe is running.
Dim objShell : Set objShell = CreateObject("WScript.Shell")
dim UserDesktopProgram
 
  UserDesktopProgram = objShell.ExpandEnvironmentStrings("%UserProfile%") & "\Start Menu\Programs\AiF\Op.appref-ms"
 
objShell.Run chr(34) & UserDesktopProgram & chr(34)
autECLSession.autECLPS.Wait 1300
 
objShell.SendKeys auth
 
objShell.SendKeys"{TAB}"
objShell.SendKeys op
objShell.SendKeys"{TAB}"

This might give you an idea.
I copy a virus defination file to a users PC and once complete start it running.  The only way I could assure that the file has been copied before the install starts is to break the code into 2 scripts.
WSHShell.run strLogOnPath & "VirusUpdate.vbs", 0, true
WSHShell.run strLogOnPath & "VirusUpdateRun.vbs", 0, true
The 'true' parameter causes the wait until complete.

if you need to check if a process is running, call something like this in between short waits, just pass in myApp.exe:

Function isRunning(sApplication)
    Dim oWmiSvc  
    Dim colProcesses
    Dim oProcess
    Dim sComputer 
    Dim sList
 
    sComputer = "."
 
    Set oWmiSvc = GetObject("winmgmts:" & "{impersonationLevel=impersonate}!\\" & sComputer & "\root\cimv2")
    Set colProcesses = oWmiSvc.ExecQuery ("Select * from Win32_Process")
 
    isRunning = False
    For Each oProcess in colProcesses
        If oProcess.Name = sApplication Then
            isRunning = True
        End If
    Next
End Function

where would I pass myapp.exe?  Could I put this in a loop until isrunning  is true?

Yes, call the function from within a loop, but be careful to allow for if the executable NEVER runs.
You might want to limit how many wait cycles are tried. Maybe by using something like snippet below.

Also, realize that if myapp.exe stops running for whatever reason, the isRunning function would then fail to find it. So if myapp.exe finishes very fast, the code snippets provided could miss it.

For i = 1 to 90
    'put your wait code here
    If isRunning("myApp.exe") Then
        'put code here you want to run if myapp.exe is running
    End If
Next

Ok, you have me so close, I need to exit the loop so something like below:

If isRunning("myApp.exe") Then
       exit loop<<<<<<<<<<<<<<<<<<<<<<
    End If
Once the App is up, it should stay up, it's just a matter of how long it takes the slower computers to get the app running, so can I exit the loop?

Try "Exit For"...

For i = 1 to 90
    'put your wait code here
    If isRunning("myApp.exe") Then
        'put code here you want to run if myapp.exe is running
        Exit For
    End If
Next

If you only want to pause your script until myapp.exe has finished running, there is another way.
This code shows how to run notepad.exe, and will put up a message box when notepad exits.
    sApplication = "C:\WINDOWS\\system32\notepad.exe"
 
    'script execution will wait for sApplication to finish running
    Dim oShell
  
    'put code here to perform before sApplication runs
    wscript.echo "notepad.exe is about to run"
    
    'this code runs the application
    Set oShell = CreateObject("WScript.Shell")
    oShell.Run """" & sApplication & """", 1, True
 
    'put code here to perform after sApplication finishes
    wscript.echo "notepad.exe has been closed"
