Operating Systems
SmartZone ICR/OCR runs on 32-bit and 64-bit Microsoft Windows operating systems:
- Windows 10
- Windows 11
- Windows Server 2012 R2
- Windows Server 2016
- Windows Server 2019
SmartZone runs in 64-bit, 32-bit, and AnyCPU-compiled executables on Windows. Although it may run, SmartZone is not supported on earlier operating system versions, such as, Windows 7.
SmartZone ICR/OCR also runs on x64 Linux operating systems of the following versions:
- Ubuntu 22.04
- Ubuntu 20.04
- Ubuntu 18.04
- RedHat 8
On Linux host machines, it may be necessary to increase the maximum shared memory segment size for heavy multi-threaded usage or processing large images. The example below demonstrates how to set shared memory segment size to the maximum possible value. See the documentation for /proc/sys/kernel for more details.
sysctl -w kernel.shmmax=18446744073692774399
On the RedHat 8 operating system, SmartZone License Manager may not work since some cryptographic protocols are disabled by default. In this case, to install a license on the local computer, required mode can be enabled with the following command (run it as a root):
update-crypto-policies --set LEGACY
After installing the license, default mode can be enabled with the command:
update-crypto-policies --set DEFAULT
