This looks to be caused by not having the necessary JAVA libraries on your system (typically the case with fresh installs of OSX as they come without JAVA by default), to fix this install the JAVA Update for OSX Lion http://support.apple.com/kb/DL1421

Once installed reboot & try installing again, if this time the installer simply hangs or beach balls on “Calculating Size” then it could be down to your user not having full rights to install services as ROOT, even though it asks you for your administrator password.

A simple way to fix this is to add your user to the WHEEL group, which is linked to root and has full permissions.

To do this, open Terminal then type:

sudo dseditgroup -o edit -u yourusername -p -a yourusername -t user wheel

Replacing yourusername with your actual username, found by typing:

id

in terminal, you should see the first line similar to this,

uid=501(johnsmith)

in this case my username is johnsmith

once done you should now see you’ve been added to the group wheel

Restart your computer and re-run the installer, it should start to install now.

UPDATE: after still more problem we found that installing Adobe Flash Player manually allowed the installer to work and finally install.

…really wish Adobe would clean up their act with this, especially with what they’re charging us for.
