  Note: CA ERwin Data Modeler support for Microsoft Windows 7 was certified on a 32-bit machine only. CA ERwin Data Modeler is a 32-bit application. You may experience problems running CA ERwin Data Modeler on a 64-bit machine unless you have the proper 32-bit drivers installed.

Administrative Privileges Required for Installation

Because the installation process for CA ERwin Data Modeler writes to the registry and system folders, the person installing, upgrading, or removing CA ERwin Data Modeler must have Administrative privileges. If you run an install without Administrative privileges, all files may not be installed or upgraded, and users will encounter problems when running the software.
