Process Start and Errors from Slow Applications - vb.net

Question

I made an application that our company uses to launch databases and updates them on the users machine, when needed.
I am having a slight problem when it comes to launching databases and the database starts up slow. When this occurs my application throws an exception, as I assuming its awaiting some kind of response back.
As of now the error thrown is: The system cannot find the file specified
I am trying to prevent this exception logging for cases like this(Slow Application), but still allow the logging if a real error occurs while opening a database.
Current Code I am using:
Private Sub OpenApplication()
If File.Exists(LocalPathString) Then ' File Found. Open the File.
Try
Dim ps As New Process
ps = Process.Start(LocalPathString)
Catch ex As Exception
ex.Source += " | " & LocalPathString
RaiseEvent ShowError(ex)
Finally
RaiseEvent CancelIt() ' Thread Complete. Close the ActionForm
End Try
Else
If LocalPathString = vbNullString Then
RaiseEvent CancelIt() ' No file exits. Cancel thread.
Else
RaiseEvent ShowError(New Exception("Database Not Located: " & LocalPathString))
End If
End If
End Sub
StackTrace:
System.Diagnostics.Process.StartWithShellExecuteEx(startInfo As ProcessStartInfo)
App.exe: N 00912
System.Diagnostics.Process.Start()
App.exe: N 00136
System.Diagnostics.Process.Start(startInfo As ProcessStartInfo)
App.exe: N 00049
SAMi.ActionClass.OpenApplication()
App.exe: N 00117

Maybe I'm missing something, but why don't you simply omit the logging if you found that specific exception?
Catch ex As Exception
ex.Source += " | " & LocalPathString
if not ex.Message.Contains("The system cannot find the file specified") Then
RaiseEvent ShowError(ex)
end if
