Operating System Support

To run erwin Data Modeler it is recommended that you have the latest version of one of the operating systems (32-bit or 64-bit) installed:

• Microsoft Windows Server 2008 R2 SP1
• Microsoft Windows 7 SP1
• Microsoft Windows 8.1
• Microsoft Windows 10
• Microsoft Windows Server 2012, R2
• Microsoft Windows Server 2016

Note:

As a best practice, always upgrade your operating system to its latest available version.

erwin Data Modeler 32-bit (these notes do not apply to the 64-bit version of erwin Data Modeler) is fully compatible with 64-bit operating systems, except for the following known issues:

64-bit database drivers and clients will not work with erwin Data Modeler 32-bit. The workaround is to use 32-bit database drivers and clients even if running in the 64-bit operating system environment.

Running the erwin Data Modeler 32-bit API in a 64-bit environment requires some changes to the workstation registry. For more information about changing the registry, see the erwin Data Modeler Workgroup Edition Implementation and Administration Guide.
