Was EA database used while installing Prolaborate? Are these tables [AccessRights table and t_attribute table] present in the Prolaborate database?
If yes, the databases are configured incorrectly.
Kindly follow the steps to configure a new database for Prolaborate application.
- Create an empty database called Prolaborate
- Choose MySQL/Microsoft SQL Install schema from this page based on the database server used for Prolaborate
- Run the chosen schema in the new database
- Open Prolaborate Service Management.exe and update the database details (Typically located at C:\Program Files (x86)\Prolaborate\ProlaborateServiceManagement)

- Go to Prolaborate Health checks page and check whether there are no issues
