what is the cause of getting the error Hardware not supported?

I was trying to test simply the touch functionality on my htc wildfire.
I have written simple code to get the Touch event in Unity with C#. This is running very well in Emulator. but when I tried to transfer the simple game in my HTC Wildfire(android 2.2) it is showing the error-> “Failure to Initialize! Your hardware does not support this application, sorry!”

Device Filter: ARMv6 (…)
Graphics: OpenGL ES 1.x
