TestExecute suite runs in remote session but not in vSphere client console

 

I suggest that you check how exactly you obtain the opened pop-up in your test. On different computers, it can take TestComplete different time to fully recognize this pop-up. That's why, the test passes on one computer and may fail on another one. So, it's better to use WaitWindow (or another Wait method) to obtain the control and only after that click a button inside.
