TestComplete unable to identify any object - C++ Application

Hello All;

I am a very new user to this product and was wondering if there are any helpful tips to get TestComplete to recognise my application.

The application I would like to automate is a Point of Sale application based on C++. This is a legacy product but is still in mass use today.

When I attempt the Object Spy on the window it can only discover the whole application (runs in Full Screen) (POS1.JPG).

I get a UIAObject for the application (Compris_GPOS) with a blank visualisation.

I am unable to record any clicks or screen outputs past this and a little stumped.

We have been informed that the application may not be suitable for automation, but looking on the SmartBear website is states ANY 32/64bit application, so a little confused.

Any tips would be greatly received.

Many thanks
