I tried to reinstall the way you mentioned, but the following message appeared:
"Alert. Aperture 3.0 or later is require to install this update"
So I moved again from the Trash folder to the Applications folder (I have 57 GB of photos in my Library and I don't want to lose them).
Each time I re-opened, the following message appeared:
"Aperture has detected inconsistencies in your library. Please click Repair to avoid any potencial problems"
And after click on the Repair button, the following Crash Log:
