use of shell command in Visual Basic Express 2008

I am writing a program in Visual Basic Express 2008. I need to call an executable using a button click. I have two buttons in the program. . Somehow the executable does not seem to run. If I run the executable from the command line it always works and throws up a menu in the screen. When called from my visual basic program nothing shows up the screen. What am I doing wrong? The second button which calls calc.exe always works.The code is shown below. If I replace the content of the shell for button1_click with the pathname for calc.exe, then that runs.
Public Class mgmt_suite
 
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MgmtSuite.Click
        Shell("C:\L1Applications\bin\L1-IMS", AppWinStyle.MaximizedFocus)
    End Sub
 
    Private Sub Global_traveler_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Global_Traveler.Click
        Shell("C:\Windows\System32\calc.exe")
    End Sub
 
    Private Sub mgmt_suite_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
 
    End Sub
End Class
