Late night expansion pack not opening

i've been trying to install late night on sims 3 but the installer doesn't open and doesn't show any error messages.
The only thing i've found this message in the console:

2/25/13 4:31:42.452 PM com.apple.launchd.peruser.1202[148]: ([0x0-0x610610].com.transgaming.tginstal… Job failed to exec(3) for weird reason: 13

I have no idea how to fix this and i would really appreciate some help

I get same trouble
