Operating System Support

CA ERwin Data Modeler requires that you have the 32-bit version of one of the following operating systems installed:

• Microsoft Windows Vista
• Microsoft Windows Server 2008 SP2
• Microsoft Windows Server 2003 SP2
• Microsoft Windows 7
• Microsoft Windows 8
• Microsoft Windows 2012
• Microsoft Windows XP SP3: As Microsoft has dropped support for Windows XP, CA ERwin Data Modeler will no longer be tested for compatibility with that operating environment. Should you encounter any problem(s) using CA ERwin Data Modeler you should first verify that the problem(s) encountered are not related to an unsupported operating environment before reporting the problem(s) to CA.

  Note: CA ERwin Data Modeler is a 32-bit application and is fully compatible with 64-bit operating systems, except for the following known issues:

  • 64-bit database drivers and clients will not work with the application. The workaround is to use 32-bit database drivers and clients in the 64-bit operating system environment.

Running the CA ERwin API in a 64-bit environment requires some changes to the workstation registry. For more information about changing the registry, see the CA ERwin Data Modeler WE Implementation and Administration Guide.
