Hi Johny,
I would recommend to use scripts & not to use Recored and Play method.
The problem you are facing now is because you have not set Delay between 2 steps.
The test completed hasexecuted the steps to open the "Tested" application but in reality , it take time to lauch that application (some splash screen will appear first & then the MainWindow of the application) . By the time the "Tested Application" gets really lauched on the screen , the TestComplete executes next statement , which will ultimately fail as the application is not launced completely.
Johny , I would highly recommend you to create the script and launch the appliction.
There are some really useful functions that you can use to wait until the particular object get exists.
If you are stick record and play method , you have to insert Drag and Drop "Delay" statement for better stability of the test.
TestComplete does work perfectly fine with some really heavy Engineering applications.
I hope this has been of some help.
