C:\Program Files\Manufacturer\Endpoint Agent>flrinst.exe -op=install -package=rsplugin_flexresponse.zip

Failed to read database schema.
Database access problem or Plugin Installer is not compatible with this endpoint version.

This installation failed because the plugin version was older than the Endpoint Agent version so they were incompatible.

You can check the version of you plugin by right clicking on the plugin file and view Properties and Version.
