Outlook object settings acting weirdly!!

[VBDotNetProgrammer]

Hi, im using the following code to launch outlook
{
Dim proc As New Process()
Dim pRunningProcesses() As System.Diagnostics.Process = System.Diagnostics.Process.GetProcessesByName("outlook&quot

if pRunningProcesses.Length = 0 Then

'Make outlook invisible
proc.StartInfo.FileName = "outlook.exe"
proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden
proc.Start()

End If
}

The problem is that where im setting the window style to hidden works on my development machine and hides the app but any other machine i test it on it doesnt!

It's like it ignores the

proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden

command all together!

Anyone know why this is?

Thanks
