Davinci Resolve 12 Beta 1 - 11 Database not detecting

After upgrading to Davinci Resolve 12 Beta 1, Unable to detect 11 database. When I try to create a new disk base database and try to connect it, Resolve opens without showing any window and try to quit many times. Not working.

Any clue how to prepare 11 database for 12?

First.. in v11, did you back up your database before upgrading to the beta?
If not, I recommend installing v11.3 and find the projects, make sure they are there, then back up the database. Even export projects you may need in the next 30 days. If you are using disk database as most users are this is a simple folder backup. Details in the manual.

Now with the database secure, install v12 beta. It should automatically find the database if you haven't moved it.
If you have put it somewhere else, page 1067 of the manual details where you should put it for Mac/Windows.

If your v12 can't see the database and its in the correct place, please let us know again and detail what system you have.
