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.


But before you download it again make sure that:


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