I just downloaded OS X Lion DMG and am trying to install it.

When i double click on the DMG file a new window popups with setup instructions. After choosing a disc drive target to install on to I get the following message:

An error occurred while preparing the installation. Try running this application again.

Is the DMG is corrupted or do I need to give any special permission to it to use it to install Lion?


After doing research i found very useful answer and following this answer now, i have installed OS successfully.
