MS-Access Connection

I am trying to access the MS-access file from S3 location. But when i am trying to access i am getting the below error message. i suspect there is something wrong only on the JDBC URL from the Generic Database Account connection. Below is my URL.

JDBC URL : jdbc:access:///S3:///umg-ers-royalties-uat/RoyNEWSCA5.accdb

Note: i am able to access flat file through the same S3 location. Please advise
