The following are the minimum system requirements for FlexProof E 12.1.x. Exceeding these requirements will in most cases lead to a performance increase. Running FlexProof E on a system that does not meet these requirements is not supported.

Minimum requirements

Minimum System Requirements for FlexProof E 12.1.x
Processor type and speed

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


Minimum 4GB RAM + 2GB per additional output device.

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 needs 50GB of disk space for installation. Also take into account the need for storage of temporary and production data. Recommended minimum 200GB. A backup solution is strongly advised. Please note that the software install location can be customized (typically c:\Program Files) but the temporary and production data is always in a standard location (x:\Documents and Settings\All users\Application Data...).
Graphics card and video driversMinimum 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.
VirtualizationNot supported.
File serversAll 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.
