The following are the minimum system requirements for FlexRip 12.1.2 Exceeding these requirements will in most cases lead to a performance increase. Running FlexRip on a system that does not meet these requirements is not supported.

Minimum requirements

Minimum System Requirements for FlexRip 12.1.2
Processor type and speed

x86 (32-bit) or x64 (64-bit) compatible dual-core processor (Intel or AMD), minimum dual-core.


Minimum 2GB RAM + 2GB per additional dispatcher.

For more info about memory limitations in Windows operating systems, please consult this table.

Available hard drive space

An NTFS volume is required. The software takes about 20GB of disk space. Also take into account the need for storage of temporary and production data. A backup solution is strongly advised.
Minimum screen resolutionMinimum 1280 x 1024 resolution, true color depth.
Network connection10/100/1000 Base-T Ethernet, TCP/IP v4 protocol, TCP/IP v6 protocol is not supported.
File servers

All Esko applications running on Windows OS can use data that is available on network shares. These shares need to be on Windows or Unix/Linux (using SMB) file servers. We recommend to use Windows Server 2003 or Windows Server 2008 as file server. 

Mac OS X (version 10.5.x; 10.6.x, 10.7.x) data servers are also supported, but with limitations. These are standard limitations encountered when connecting to a Mac OS X server from Windows workstations or servers. They are related to losing resource forks of the MAC-application data when a Windows component moves or copies data.

We highly recommend to use Windows file server.

  • VMware ESX version 3, 3.5, 4, 4.1, 5 and 5.1
  • Microsoft Hyper-V

Hardware connections, including dongles, proofers, spectrophotometers and others may work, but are not supported. Customers should verify hardware support through their virtualization support channels.

Known issue

When you run software (with a local license server) on a virtual machine, the Esko license server (a process called “esko.exe”) might take up 100% of one of the virtual processors. This problem has been escalated to the third-party who provides the licensing engine, but currently we can only offer two workarounds:
 - Reboot the virtual machine if this problem occurs.
 - Move your Esko license server to another (and preferably physical) machine.
