I am trying to upgrade our product line to .net 4.0 and vc10, to guarantee no big problems, I installed TestComplete 7.5 to run QA’s test scripts against the new build. In the past upgrade of 64bit, this worked well and most of the bugs had been identified.
While due to unknown reason, my TestComplete just hangs after starting, and works well on QA’s machine, really kind of headache. Then, attached it with windbg, and also analyzed it with spyxx, finally found TC just being blocked at NtUserGetMessage function, after dumping the memory block the first arg points to, the window handle can be found and it is an “internet_explorer_hidden” by verifying with spyxx, seems belonging to splash screen.
Checking the command line option, and found “/ns” can start TC without splash screen. Try and it works
Just record it for other guys who may also face the same problems.
