My initial thought is that you may need to double check your compiler settings for your application. Some changes may be required in how you compile the application.
That old thread you mentioned is for TestComplete 10... it's 4 years old so any patches or anything involved with that instance won't apply here.

Why automate? I do automated testing because there's only so much a human being can do and remain healthy. Sleep is a requirement. So, while people sleep, automation that I create does what I've described above in order to make sure that nothing gets past the final defense of the testing group. I love good food, good books, good friends, and good fun.
