aTVFlash Installer says Java runtime is missing (Mac OS Lion)

When I start the aTVFlash Installer (whether from the disk image or from the applications folder) I get this message:

To open “aTV Flash,” you need to install a Java runtime, but you are not connected to the Internet.

The Network Diagnostics show that the Internet connection is OK.

Mac OS X 10.7.2 (Lion)

AppleTV 3.0.2 (8N6014)

I’ve found the solution:)

OS X Lion doesn’t install Java - you have to install it yourself from http://support.apple.com/kb/dl1421

After installing Java the application starts!
