Supported Platforms

To run Circuit Design Suite 14.1, your operating system (OS) must be one of:

  • Windows 10, 8.1 or 7 SP1.
  • Windows Server 2012 R2.
  • Windows Server 2008 R2 SP1.

  • Pentium 4 G1 (or equivalent) or later (64-bit).
  • 1 GB of memory.
  • 2 GB of free hard disk space.
  • 1024 x 768 screen resolution.
  • To develop custom LabVIEW-based instruments for use in Multisim, LabVIEW 2015 or 2016 is required.

Installing Circuit Design Suite 14.1


  • If Windows Update is enabled, the installation process might hang if Windows Update interferes with the installation of Microsoft Visual C++ 2015 Run-Time. Visit and enter the Info Code exjq43 for more information and steps to resolve this issue.
  • If you purchased this product with an NI Software Suite or NI Product Bundle, use the installation media that shipped with your purchase to install this product.

Installing Multiple Versions

Circuit Design Suite 14.1 installs side-by-side with Circuit Design Suite 13.x and prior.

Archiving Circuit Design Suite databases

National Instruments recommends that you regularly back up the files created within the Multisim and Ultiboard components of NI Circuit Design Suite. Additionally, you should back up internal files that store user-created data, such as databases. For more information about which files to backup and where to find them, refer to the Help.


Uninstalling Circuit Design Suite will not remove user data. For more information about the locations of user database and configuration files, refer to the Archiving Data Help topic.

Automating the Installation of NI Products

You can automate the installation of most NI products using command-line arguments to suppress some or all of the installer user interface and dialog boxes. However, starting with the August 2012 releases (products using NI Installers version 3.1 or later), you may need to perform additional steps before or during an automatic installation of NI software.

If the NI product you are installing uses Microsoft .NET 4.0, the .NET installer may run before any NI software installs and may require a reboot before the installation of NI software begins. To avoid a .NET reboot, install .NET 4.0 separately before you install NI software.

For more information, refer to the following KnowledgeBase articles:

Using NI Software with Microsoft Windows 10

Microsoft Windows 10 is the latest version of the Windows operating system and features significant changes compared to previous versions. Windows 10 introduces several new capabilities and also combines features from both Windows 7 and Windows 8. For more information about NI support for Windows 10, visit

Using NI Software with Microsoft Windows 8.1

When you install NI software on Microsoft Windows 8.1, you will notice a few additional tiles on the Start screen, including shortcuts to NI application software products.

Using NI Launcher

NI Launcher helps you find and launch installed NI products. It provides you with a method of finding NI products similar to the Start menu in previous versions of Microsoft Windows. To use NI Launcher, click the NI Launcher tile on the Start screen. NI Launcher launches the desktop and opens a menu containing a list of NI products. Click any NI product to launch it.

Pinning Frequently Used Applications

For convenience, you can pin your most-used NI applications to either the Start screen or the Taskbar on the desktop, as necessary:

Current ApplicationIcon LocationPin to Action
Windows 8.1 DesktopDesktop TaskbarRight-click application and select Pin to Taskbar
Windows 8.1 Desktop Start screenRight-click application and select Pin to Start
Windows 8.1 Start screenDesktop TaskbarRight-click application and select Pin to taskbar from the menu bar on the bottom of the screen

Finding All Programs

If you want to find a particular application or related files, such as documentation files, from the Start screen, you can access all installed files by right-clicking anywhere on the Start screen and selecting All apps. A list of all installed software and related files appears, in alphabetical order by creator or type.

Known Issues


LabVIEW functionality (LabVIEW instruments and grapher interpolation) will not work if the installation path uses characters that are not native to the "Language for non-Unicode programs" setting, available by selecting Start»Control Panel»Regional and Language Options and selecting the Advanced tab. In the Vista OS, use the "Current language for non-Unicode programs:" setting in the Administrative tab. LabVIEW functionality works for Unicode characters that are native to this setting.

Circuit Design Suite

Multisim and Ultiboard leak GDI resource handles when used over extended periods of time, eventually leading to unpredictable user interface behavior and crashes. This is an issue with MFC applications running on Windows XP SP2 and Windows Server 2003. For more information and workarounds, refer to KB 4JREGSXL:Multisim or Ultiboard Leaking GDI Resource Handles.

Multisim Help and Ultiboard Help display in very small windows on high resolution monitors (e.g., 3200 x 1800). To enlarge the windows, click in a help topic, hold down Ctrl and spin the mouse wheel. For notebook computers with precision touchpads, hold down Ctrl and use pinch-in and pinch-out gestures to zoom to the desired level.
