7.3 Database query error on installation

I know its early but i keep my self busy by testing dolphin repositories to find out whats new and whats missing. Yesterday i tried to install a fresh copy of dolphin from repository and found this

Database query error right after the Inc permission page. With old repositories i didn't found this error. One more thing if i open a new page and enter the ip address, it will take me to the delete install folder page.  after deleting the install folder if i want to go to admin panel i get this error

Fatal error: Cannot apply localization.

Just sharing incase you guys missed some thing or may be 7.3 installation requirement changed

I got the same - it seems something to do with the language files not being installed etc

I tried several times but could not figure it out.

I have never had any kind of installation issues in the past with any version

hopefully someone can help.

server 500  error... looks like it dies.. LOL..

 I'll have to reinstall boonex again...

Remember, it is a work in progress.

How can you post an error, then expect someone to help you fix it, for something that is being worked on?

 I don't need any help cause i am not using it for live site. i was testing and sharing my feedback to help out. Thats why i posted in pre-release testing. 7.3 Beta will be out soon, so i was just trying to give a hand before the beta release. Actually there is no other way except creating an issue in github to communicate. I know they would have figured it out before the beta but just to save their time

The same problem remains in the Beta version too which I tried today

 plz wait till end of the week. Beta is not out yet. i just check in my own way that may not apply to your situation, specially if you want to try it to live site. I play on an offline server.

This is the release I tried today?
