Excel VBO Run macro async is not working

[立晨姚]

Below is the stage code :

macroNameParam = MacroName
handleParam = Handle      'instance number

threadObject= New System.Threading.Thread(AddressOf RunMacroAsync)
threadObject.Start()

It works for my former employer. But it is not working for my currently employer. It just run over this stage and Macro did not kick off and no error show up.
Any idea what could be the issue?

The code for RunMacroAsync is:

Private Sub RunMacroAsync()
try
GetInstance(handleParam).Run(macroNameParam)
catch ex as exception
end try
End Sub

Just to check are all the Excel add-in/trust/macro settings are the same for both the machines ?
