NI-DCPower versions are now aligned with the versions of major NI application software products. This alignment gives you information about the year the driver was released and the most recent software version the driver was designed to work with. Driver versions now start with a two-digit year indicator: <ProductName><Year-BasedVersion>. For example, NI-DCPower 15.0 is the version released with LabVIEW 2015. The last version released under the old numbering scheme is NI-DCPower 1.9. The first version released under the new numbering scheme is NI-DCPower 14.0.
Perform the following procedure to uninstall NI-DCPower 15.1:
For Windows XP, complete the following steps:

The following items are changes in NI-DCPower 1.9 from NI-DCPower 1.8.
|404741||Under certain configurations, the NI PXIe-4154 could inadvertently toggle from remote sense to local sense, then back to remote sense at NIDCPower Initiate, forcing the user to add additional settling time before taking a measurement. This has been resolved.|

|286821||Fixed an issue in which you must run LabWindows/CVI with elevated privileges to successfully launch the NI-DCPower Simultaneous Update example from LabWindows/CVI. NI has renamed this example to NI-DCPower Simultaneous Operation, and you no longer need to run LabWindows/CVI with elevated privileges to launch this example.|
|371368||Fixed an issue in which temperature changes degraded the output accuracy on the NI PXI-4132. You can now self-calibrate the NI PXI-4132 to maintain output accuracy.|
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 a silent 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 about automating the installation of NI products, refer to the following KnowledgeBase articles:
When you install National Instruments software on Microsoft Windows 8.x, you will notice a few additional tiles on the Start screen, including shortcuts to NI application software products such as NI LabVIEW, Measurement & Automation Explorer (MAX), and the new 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.
|Note MAX does not appear as a desktop shortcut when installed on Microsoft Windows 8.x. You can launch MAX either from the Start screen or from within NI Launcher.|
For convenience, you can pin your most-used NI applications, such as MAX, to either the Start screen or the Taskbar on the desktop, as necessary:
|Current Application||Icon Location||Pin to Action|
|Windows 8.x Desktop||Desktop Taskbar||Right-click application and select Pin to Taskbar|
|Windows 8.x Desktop||Start screen||Right-click application and select Pin to Start|
|Windows 8.x Start screen||Desktop Taskbar||Right-click application and select Pin to taskbar from the menu bar on the bottom of the screen|
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 from the Apps view. To get to the Apps view, right-click anywhere on the Start screen and select All apps (Windows 8.0) or click the down arrow on the bottom left of the screen (Windows 8.1).
For more information about NI support for Windows 8.x, visit ni.com/windows8.
National Instruments NI-DCPower will drop support for Microsoft Windows Vista, Windows XP, and Windows Server 2003 as of July 1, 2016. Versions of NI-DCPower that ship after July 1, 2016 will not install or run on Windows Vista, Windows XP, or Windows Server 2003.
