This section provides information about the hardware requirements for the VRS 4.2 product. Before installation, ensure that your computer meets the minimum requirements. Using the recommended requirements will help to assure optimal performance.


VRS 4.2 System Requirements

Minimum Hardware Requirements

The following lists the minimum hardware requirements for VRS 4.2:

  • Processor: Pentium 4, 1.4 GHz
  • System memory: 256 Mbytes or more
  • Disk space: 300 Mbyte free disk space for installation
  • Display: Monitor resolution: 800 x 600
  • CD ROM drive
  • Web browser: Microsoft Internet Explorer 5.01 (or higher).

Recommended Hardware Requirements

The following lists the recommended hardware requirements for VRS 4.2:

  • Processor: Intel Core 2 Duo/AMD Athlon 64 X2
  • System memory: 2 GB
  • Disk space: 250 GB (7200 rpm)
  • Display: Monitor resolution: 1024 x 768
  • CD ROM drive
  • Web browser: Microsoft Internet Explorer 6

    Note: The VRS 4.2 installer checks to determine if Microsoft .NET Framework 2.0 exists already on your computer.  If not, Microsoft .NET Framework 2.0 is installed automatically during the VRS installation.  If other applications on your computer rely on the Microsoft .NET Framework, you should verify that the installation of version 2.0 does not introduce any compatibility issues.  For more information, refer to your Microsoft .NET Framework documentation.


TWAIN and ISIS Considerations

All VRS scanners are supported by either TWAIN or ISIS drivers. Although some of these scanners will work with both TWAIN and ISIS drivers, only the driver that works best with VRS will be certified and supported. If your scanner is certified with a TWAIN driver, refer to TWAIN Installations on page 46 and follow the instructions that apply to your scanner. It is not necessary to install an ISIS driver, as VRS includes all the necessary ISIS software to control the certified scanners.


USB and FireWire Considerations

Some VRS scanners are supported by a USB or FireWire interface. If your scanner requires a USB or FireWire interface, there may be specific installation instructions that apply to your scanner. Refer to USB and FireWire Installations on page 47 of the VirtualReScan (VRS) 4.2 Installation Guide for more information.


PCI Slot Requirements

Before installing an Adrenaline SCSI scanner controller, make sure that your computer includes a PCI slot that meets the following requirements:

  • 5 Volt PCI slot that can accommodate the length of the controller (175 mm)
    This short length is not the same as the Low Profile PCI (LPPCI) specification.
  • 32-bit transfer connector (minimum)
    A 64-bit transfer connector may be used, as long as it uses 5 Volt signaling.

Peripheral Support

To be properly supported by Kofax, your scanner must be certified. To determine if your scanner is a certified device, use the Kofax Scanner Configurator by clicking here.


Certified Interfaces

USB, SCSI, and FireWire interfaces are certified with VRS 4.2.


Certified SCSI Scanner Controllers

Review the informaiton in the VirtualReScan Scanner Certification list to determine the VRS 4.2 supported SCSI scanner controllers.


Desktop Productivity Features

The VRS 4.2 Desktop Productivity features are available from Windows Explorer or Windows Desktop, as well as the following email applications:

  • Microsoft Outlook 2007
  • Microsoft Outlook 2003
  • Microsoft Outlook XP (also called Microsoft Outlook 2002)
  • Lotus Notes 6.5

Installation Scenarios

If you currently have VRS 3.5 (or later) installed, you can successfully upgrade to VRS 4.2 without removing your existing installation. If your current VRS installation is a version released prior to VRS 3.5, you must upgrade to VRS 3.5 before upgrading to VRS 4.2. If necessary, do one of the following to verify your existing VRS version:

VRS 3.5 or earlier – Select the About tab from the VRS Interactive Properties dialog box.
VRS 4.0 or 4.1– Select Help | About from the VRS Interactive Viewer menu bar.

For more information about removing VRS, refer to Removing VRS on page 61 of the VirtualReScan (VRS) 4.2 Installation Guide. For details about upgrading your VRS 3.5 or VRS 4.x installation, refer to the VirtualReScan (VRS) 4.2 Release Notes.


Certified Scanners

VRS and Kofax Capture

VRS 4.2 is installed “silently” as part of all Kofax Capture (formerly called Ascent Capture) installations. Therefore, it is not necessary to install VRS separately if you have a Kofax Capture installation already in place. When installed silently with Kofax Capture, VRS does not appear on the “Currently installed programs” list in the Add or Remove Programs utility (or the Programs and Features utility on a Windows Vista computer).

For details about the Kofax Capture installation process, refer to the Kofax Capture documentation.
