It is recommended that you run kenaflow on a virtual machine to match the resource requirements to the workload.

The following requirements apply to the physical or virtual hardware:

Minimal System Requirements

  • 2 CPU or cores

  • a minimum of 8GB RAM

  • 4 CPU or cores

  • a minimum of 12 GB RAM

Operating System

kenaflow runs exclusively on computers with a 64-bit Windows operating system. Please make sure that you meet this basic requirement.

kenaflow normaly runs on server operating systems:

  • Windows Server 2008
  • Windows Server 2008 R2
  • Windows Server 2012
  • Windows Server 2012 R2
  • Windows Server 2016
  • Windows Server 2019

"Core" editions of Windows Server are not testet currently. Mainly this is because workflow development requires a development tool such as PowerShell ISE or Visual Studio Code.

You can try it by installing Server Core App Compatibility Feature on Demand (FOD) (a Microsoft page) on "core" and see if it works for you. - We would be happy about feedback!

kenaflow also runs on client operation systems:

  • Windows 7
  • Windows 8
  • Windows 8.1
  • Windows 10

It is not recommended to run kenaflow on a computer with other software products. Depending on the workload and various settings in the software, kenaflow can be very resource-intensive.

In particular, no web server (e.g., IIS) should be running on the same computer.

Server Side Storage

The drive on which kenaflow is installed must have about 2GB free space for the program files.

kenaflow generates logfiles during execution, which can become very large depending on the load. For this, 30GB of space should be provided.

By default kenaflow will be installed in the following directory C:\Program Files\kenaflow.

In the default configuration, kenaflow stores the execution data - e.g. log files in a subdirectory of C:\ProgramData\kenaflow.
