I was happily using version 2.0.16 with sqlite on windows but cannot test my application with 2.1 version because:

php.exe app/console doctrine:database:create

does not work anymore.

I am receiving:

Could not create database for connection named "esgrcwaredbviewer"
SQLSTATE[HY000] [14] unable to open database file

parameters:
database_driver: pdo_sqlite
database_host: localhost
database_port: ~
database_name: esgrcwaredbviewer
database_user: esg
database_password: esg
path: t:/wwwroot/RcWareDBViewer/db/esgrcwaredbviewer.sqlite

Same configuration and everything works just fine with the previous version. I believe that it is not a permission related issue.
