Invalid Package File when installing

Hi,
I also have a Samsung GT-S7500 with 2.3.6 and installed the posted apk but as soon as I open it the generic "app unexpectedly stopped" error pops up and I have to hit "force close". It doesn't seem to generate any log files or at least I can't find one. My phone isn't rooted though. Do phones only show log files when rooted?

ain't no log, phone is rooted.

same problem with samsung mini 2

I'm having the same problem in a galaxy ace GT-S6802 Duos

Version 2.3.6
