I can’t install iTunes10.5.x (Solved)

Hi
I wanted to update itunes to 10.5.x and in the middle of installation my computer froze forcing me to restart the computer. Now when I try to install iTunes it starts at “Installing Bonkour…” etc and says errors occurred and to run installer again. I tried running it again and it just repeats the same process. Is there any way to get it to install from the “beginning”? Thx alot.
