Hi,
Is it the very first test that fails with this error or some subsequent (second, third, ...) one?
The reason for my question is that according to, say, https://social.msdn.microsoft.com/Forums/vstudio/en-US/70ef972b-51b6-4ece-a4af-d6b4e111eea5/msword-automation-error-the-message-filter-indicated-that-the-application-is-busy?forum=vsto or http://stackoverflow.com/questions/23707475/dcom-config-settings-for-microsoft-interop-word-automation, the 0x8001010A error means that the server is busy and rejects to serve the request.
In case of TestExecute this may mean that TestExecute completed execution of first test but is busy unloading from memory or something like that while Spira does not wait enough / does not do proper checks to wait until it is safe to start the next test.
Just my guess...
