Issue

• When installing Kaspersky Scan Engine for Windows, you can encounter the “SCRAM authentication requires libpq version 10 or above” error.

Cause

• The default password encryption mechanism has been changed in PostgreSQL 13 database management system. The initial postgres user that was created during the PostgreSQL installation has a password encrypted with the scram-sha-256 algorithm. This algorithm is not supported by Kaspersky Scan Engine for Windows.

Solution

• We recommend that you use PostgreSQL version 11 or 12.

If you cannot use the recommended versions, configure the supported password encryption mechanism in PostgreSQL. Instructions for the following installation scenarios:

• • Installation using the installer (Windows)
  • Manual installation (Windows)

The changes will affect the entire PostgreSQL cluster and other applications that use the cluster.
