Install iPhoto '9 on Mountain Lion I just received my new iMac, with Moutain Lion and iLife 11 preinstalled.

I also own an older Mac, for which I bought a few years ago Snow Leopard and iLife 09.

Now, I want to get rid of iPhoto 11 and reinstall my good old iPhoto 9 as I like it much better.

I tried to reinstall it with the iLife'09 DVD I have, but the installer doesn't let me install iPhoto (and iMovie), but would let me install iWeb.

Is there a workaround so that I can use iPhoto 09 on my new iMac ?
According to a similar thread on Apple Discussions, yes, iPhoto does work on 10.8.
Try deleting the troublesome applications - and that way they should install.
What do you mean 'it won't let you install iPhoto'? How doesn't it let you install it?
