I'm having the same issue... my log is exactly the same.
this you solve the issue? i've downloaded the DMG 3 times
I did solve the problem actually. Turns out something on my MAC was
preventing it from installing. My only solution was to reinstall snow
leopard. Make sure you have everything backed up in time machine. Good luck.
Thats something i cant do a windows solution for a mac problem
im googling and i cant find wich program is in conflict with adobe cs5
If I knew, I'd tell you. Sadly I do not. Maybe re-installing Windows (insert version here) will help you too. It is possible for Adobe CS5 to have the same bug or problem, cross platform
