DB2 10.5 for Linux, UNIX, and Windows

Beta and non-beta versions of DB2 database products cannot coexist

A DB2® copy can contain one or more different DB2 database products, but it cannot contain both beta and non-beta products. Do not install beta and non-beta versions of DB2 database products in the same computer.

This restriction applies to both client and server components of DB2 database products.

Resolving the problem

Uninstall the DB2 beta version before installing the non-beta version or else choose a different installation path.
