i'm trying to install 4.0 from https://download.moodle.org/releases/development/ into my xamp installation. 

Installation breaks after the page where I can select database, database user and database pwd. After that I get the the "error reading from database" error. 
Moodle database is created, config file too. 

I'm on windows 10 64 bits. I've latest xamp version (uninstalled / reinstalled), but before I had the same error with older xampp versions.  I've got same problem with other brothers. 

Logs says : 
Table "context" does not exist

I've tested with another computer (windows 10 64 bits). fresh xampp install, latest package from moodle and installation was fine.
