Homer Pro System Requirements
HOMER Pro and HOMER Grid are Windows-based applications that requires Windows Vista or “above,” i.e., Windows 7, 8, 8.1, or higher. It will not run on Windows XP. (Windows XP users must use HOMER 2.)
HOMER Software requires Windows with the .NET 4.6 framework. Windows Vista, 7, 8, and 8.1 users will likely need to update their .NET framework to 4.6. If you need to update your .NET framework, you can do so here.
HOMER may run on Mac systems with an appropriate Windows emulator, but we do not support those installations.
Starting with version 3.9.0, we recommend the 64-bit version for most users. It runs up to 30% faster and supports 1-minute time steps. However, you may install and operate both versions on one computer using the same license.
HOMER will run on a Macintosh equipped with a virtual Windows environment with the above operating systems, but we do not provide support for that environment.
