Bug 38057837

When installing a 32-bit Oracle Database Client in the same Oracle base directory as an existing 64-bit Oracle Database Client, the installer revokes permissions for non-Administrator users on the 64-bit client home. Consequently, non-Administrator users may receive Access is denied errors when attempting to run executables, applications, or graphical user interface (GUI) tools associated with the 64-bit client installation.

Workaround:

To avoid permission conflicts, install 32-bit and 64-bit Oracle Database Clients in separate Oracle base directories.
