Unfortunatly, the new beta version changes nothing to my problem with the installer. It stall always at same place, just at the moment where it is suppose to do this action: RepositoryManager: lock acquired on: /Library/Preferences/.com.zerog.registry.lock
I don't have this invisible file /Library/Preferences/.com.zerog.registry.lock. I had it before having problem with the installer but I deleted it because I thought it was the source of the problem. I hope you will find a solution to this problem .
