System Requirements

Registry Plus programs work with 32- and 64-bit Microsoft® Windows® operating systems on x86-compatible processors. The minimum hardware requirements are the same as those of the Microsoft Windows operating system used.

Additional system requirements include—

  • Microsoft® Windows® operating environments: Windows 7/8/10.
  • 2 GB RAM.
  • Latest version of Microsoft Internet Explorer (recommended).
  • At least 1 GB of free hard disk space.

Installing and Upgrading Utility Programs

Before you install or upgrade Utility Programs, please read the following information.

  • Individual Northcon conversion installations can be stored on the same computer. Installing Northcon160 will not overwrite prior versions of Northcon.
  • If someone else is responsible for maintenance of your computer, you may not be able to install software. In this case, consult the maintainer of your computer for assistance. If you are installing programs on Windows XP, you must be logged on as the administrator. If you are installing programs on Windows 8, you will be prompted to enter an administrator user ID and password.
  • If you are upgrading or reinstalling an existing version of the Utility Programs, uninstall the existing Utility Programs according to the procedures of your operating system.
    When Northcon160 is uninstalled, the RPlusRPUtils folder will remain, but the Northcon160 folder will be deleted. No Northcon database or configuration settings will be preserved. The default installation folder is C:RegPlusRPUtilsNorthcon160. You may install the Utility Programs on the drive and folder of your choosing; however, the location will not be preserved for subsequent installations.


The Utility Programs are delivered via an installer .exe file, which includes documentation and supplementary files useful for programming and linking the programs to existing systems.

  1. Download Utility Programs to your computer.
  2. Open the downloaded file to access the software and its documentation.
  3. When installed, click the Windows Start button and select Northcon160, or navigate to the Registry Plus group and select Northcon160.
