UniBeast has detected that your purchased copy of "Install OS X Mountain Lion.app" is incomplete.

You need to download it again from the Mac App Store.

Before you download it again, make sure that:

1) You only have one copy of "Install OS X Mountain Lion.app" and it's in /Applications
2) Your system language is English
3) You are not using case-sensitive filesystem for /Applications or the target volume
