AD Audit Plus migrate to MS SQL

AD Audit Plus migrate to MS SQL

I try to transfer the database to MSSQL, but every time I get an error:
[SYSERR]|[INFO]|[36]: java.sql.SQLException: Cannot find the symmetric key 'ZOHO_SYMM_KEY', because it does not exist or you do not have permission.|

The rights of the sql user are sysadmin. The instructions say nothing about 'ZOHO_SYMM_KEY'. Also, the command specified in the instruction does not work - GRANT CONTROL ON CERTIFICATE:: [ZOHO_CERT] TO [newly_created_user]

Please tell me what is the problem and how to solve it.
