Error DBMRfcCommuncicationError at DB Instance CreateObject

Question

Hello!
I would like to set up the MTE MaxDB to monitor the SAP DB from SAP Solution Manager.
If Itry to execute DB50 --> Properties I get the error "DBM_CONNECT".
Error DBMRfcCommuncicationError at DB Instance CreateObject
How can i activate the MTE MaxDB?

Hello!
Thank you for your response!
The execution of "dbmcli" with additional parameters "-s dbm_version" retrieves
"External program terminated with exit code 128"
How can I check whether I have or not the DB client?
What is the URL-destination I can download DB client software?
