I am using ETABS V18.1.1 & RCDC V09.00.00.21, there is an issue while importing the .mdb files in RCDC V09.00.00.21 it shows an error "unable to read analysis". Also I am using the latest access database runtime engine. Following are the attachments for the reference.
Hello Sir,

We would also recommend you to upgrade your RCDC to latest version i.e. 9.1.1.4.
