We have customized Word addins which open some .Net-based windows. When I try to use the Object Spy on it, the whole application along with the word.exe process gets closed.
I think it is related to some .net framework version issue. Because after crashing I check the event viewer where I could see the error as ".NET Runtime version 2.0.50727.5485 - Fatal Execution Engine Error".
Could it be UFT 12 is not working well with.Net 4.5?
