samer wroteApple made the switch from PowerPC processors to Intel back in 2005-2006. It allowed you install Rosetta, a PowerPC dynamic translator to be able to executed programs compiled under the Power ISA on an Intel processor. Rosetta was dropped in Lion (I guess it became a hassle to port a 6 year old technology). Your best bet is to look for an Intel version of the app.
Thanks Samer for the quick reply.
Will try to look up for one.
