How to fix "Installing Agent failed"

Hi everybody,

I have deployed One Identity Manager Data Governance Edition 8.1.5 and while deploying agent i could see "Installing Agent Failed". The Data Status is "DGE Server domain service account credentials are required and not set".

It's a local windows server, i selected the path and set the schedule. I suppose the service was deployed and initialized because the values "Q1IMDBConnectionString" and "QAMAuditActivityDBConnectionString"  are not empty.

Any idea how to fix this issue?

Thank you in advance,

Miriam.
