Environment considerations

This page provides technical information about the environment in which PReS Workflow is intended to run.

Terminal Services

PReS Workflow does not support Remote Desktop (Terminal) Services because Workflow runs on single server and only one user can log on at once.

Terminal Services may also be referred to as Terminal Server or Remote Administration Mode (Windows Server 2003 and 2008).

Single-User Remote Desktop Protocol (RDP) (where only one person can use RDP at a time) is supported for PReS Workflow version 6.2 and higher, however it is only supported in Windows XP or Windows 2003. While later versions of Windows may not cause issues when accessing PReS Workflow through RDP, these combinations are no longer tested and may not be functional.

Virtual environments

PReS Workflow supports the following virtual environments:

  • VMWare Environments. This includes VMWare Player, VMWare Workstation as well as VMWare ESX Server.
  • VMWare VMotion. This means the virtual machine hosting PReS Workflow can be automatically moved from one ESX server to another in a clustered installation.
  • Microsoft Hyper-V/Azure infrastructure environments.
  • Amazon Web Services (AWS)

PReS Workflow is not officially supported on any other virtual machines such as Virtual PC, Parallels, Bochs, Xen, etc. While running PReS Workflow on these virtual machines may work fine we have not tested them and cannot offer support for them.

The PReS Workflow End-User License Agreement (EULA) specifies that a PReS Workflow software license may only be used on a single virtual or physical PC at a time. While copying a virtual machine for backup purposes is acceptable, running two instances of the same machine, using the same serial number, is strictly prohibited.

32-bit or 64-bit?

PlanetPress Suite version 7.1.3 and higher, as well as PReS Connect, support a 64-bit operating system. However, PReS Workflow remains 32-bits in this environment, which means that for all intents and purposes there is no difference between those two environments as far as PReS Workflow is concerned.

Antivirus considerations

PReS Workflow generates a very large amount of temporary data on your hard disk, especially when manipulating or creating PDF files. This can sometimes cause issues when any other software is trying to access the temporary files at the same time as PReS Workflow and its components are trying to read, write, create or delete those files.

If you experience these issues you may want to temporarily disable your antivirus "live", "daily" or "deep" scans for the following folders and processes:

Disabling any antivirus scanning permanently on any folder or program is not recommended, and Objectif Lune cannot be held reliable for any consequence of disabling your antivirus or whitelisting the folders or executables listed here, or any other change in your antivirus protection setup!

  • On Windows 7/2008 and later:
    • C:\ProgramData\Objectif Lune\PlanetPress Workflow 8\
    • C:\Users\[user]\AppData\Local\Temp\ (where [user] is the user under which Workflow is configured)

    • C:\Users\[user]\Connect (where [user] is the user under which Workflow is configured)

  • On all systems:
    • C:\Windows\Temp\
      C:\Windows\Temp\ is used by multiple software which may cause risks on your computer. However, PReS Workflow may use this folder as temporary storage, especially in the case of creating PDF files. We do not recommend disabling scan on this folder, unless you notice performance issues when generating PDFs, and then only as a test.
  • Processes:
    • FTPPutService.exe
    • HTTPService.exe
    • LPDService.exe
    • LPRService.exe
    • PPWatchService.exe
    • PSWService.exe
    • SerialService.exe
    • SMTPService.exe
    • TelnetService.exe
    • ppNode.exe
    • PPFaxService.exe
    • PPImageService.exe
    • MessengerService.exe

Backup software

For similar reasons, it is important to know that backup software can also access files while copying them to a remote backup location, so you should make sure that no PReS Workflow process is working during your backups.

Microsoft Office compatibility

The Microsoft Office 2010 line of products, other than Pro and Enterprise, has not been certified for use with PReS Workflow. Some of its products may not be compatible with the connectors included in OL Connect.
