# Server Technical Requirements

## Operating systems

* Windows Server 2008, 2012, or 2016 (all releases)
* Windows 7 / 8 / 8.1 / 10 (recommended for development environments only)

## Web server

* Microsoft IIS 7 or higher
* .NET Framework 4.6.1

## .NET 4 support

* Support for .NET web services and web forms developed by the client
* WorkflowGen software itself requires .NET Framework 4.6.1

## Minimum hardware configuration

### Hardware

* Quad-core processor
* 8 GB RAM
* SATA hard disk with 40 GB free

### Database servers

* Microsoft SQL Server 2008, R2 and Express Edition

  **Note:** While SQL Server 2008 is still supported, we highly recommend using SQL Server versions 2012 and later, since there has been a WorkflowGen performance improvement in response time when loading large paginated request or action lists that is only applicable to SQL Server versions later than 2008.
