If you cannot launch it, select it in the Finder:
And what version number is showing on your Aperture Library? Does it show as afan of three pictures, and with the filename extension ":aplibrary"?

Did you originally purchase it from the MacAppStore? Try removing Aperture from your Applications folder. Then zip it up and then delete the non-zipped Aperture file. Then re-download Aperture from the MacAppStore.
