Unable to connect to Metabase h2 DB

I can not initialize the metabase setup, as I am getting error when connecting metabase to h2 db.

I did so far as below

1.Downloaded metabase.jar from here

2.From cmd prompt i executed java -jar metabase.jar

I am getting Below error

Initially I didn't get an error. I did everything in metabase. After 2 days, when I tried the same, I am getting this error. Even after deleting everything and tried from start again and also with admin permisions. Nothing worked same error.

Solution

Try Opening command prompt with admin credentials and run the below command

java -jar metabase.jar
