I installed Lion on my MacBook Pro. Worked great.

Now I want to install it on my iMac, I don't want to re-download it from the App Store because it's a 3.5GB download and I have to pay for all my bandwidth (yes, I'm Canadian).

Is the installer executable on my MacBook Pro somewhere? If so, where is it and can I just copy it to the iMac and run it?

Thanks, Rob

Unfortunately the installer package contains the source files for the installation and this package is deleted once installation has completed.

If you still have the installer in Applications, right-click on it and Show Package Contents then browse to the /Contents/SharedSupport/ folder and look for the InstallESD.dmg disk image. This image can be burnt to a dvd saving future downloads but I am afraid you are going to have to download it again.

Unfortunately the installer is removed after a successful installation of Lion, so you'll probably need to download it again.

From another question....

Is it possible to burn a DVD out of the Lion app store install?

Joel has a nice set of instructions on how to do this.
