Hi Alex,
Thanks for the response.
Below is the answer to your question on Objects.
I had recorded a test prior to MS Access Database engine 2010_x64 installation. I uninstalled that because it didnot work.
Now I tried to run the recorded test and TestComplete is unable to perofrm the operations / identify the objects (e.g. Buttons, Textboxes etc.) of the web application. When I used object spy, it shows the same properties of the object at a different point, not on that particular button/textbox. Afterwards I tried to run the same test in a different machine, and TestComplete had no difficulties in identifying those objects.
So I am now suspecting it is caused due to /passive command-line installation of MS Access Database engine.
