That really rather depends on *how* the app is asking.  If you can tell 
us that, we can almost certainly tell you how to fool it.

Of course, if you have the source code, it should be easy as you can 
just comment out the test and recompile.

Mind you, if the app is as short-sighted and bloody-minded as its 
developers, maybe you should just look for an alternative.
