This file contains information on DIAdem 2018:
DIAdem is the National Instruments software for analyzing and documenting data from various sources.
For correct DIAdem performance, the following minimum requirements must be met:
|CPU||x64 compatible processor, 1.6 GHz or more|
|Amount of memory||2 GB or more|
|Hard disk memory||Depending on the operating system, up to 3 GB free storage space, of which at least 2 GB are on the system partition|
|Video card||Color depth at least 16-bit (High Color), 24-bit, or 32-bit (True Color) recommended|
|Screen resolution||From 1024x768 with a 100% scaling step|
Windows 10 64-bit1
Windows 8.1 Update 1 64-bit1
Windows 7 64-bit with Service Pack 12
Windows Server 2016
Windows Server 2012 R2 Update1
Windows Server 2008 R2 with Service Pack 12
|Note National Instruments recommends the use of the NI Analysis Server for the automatic evaluation on server operating systems instead of DIAdem.|
1 NI software installs VC2015 runtime and .NET 4.6.2. Windows 8.1 requires Microsoft updates to support these software products. Refer to Microsoft KB2919442 and KB2919355 for more information about how to install these updates.
2 NI software is signed with an SHA-256 certificate. Under Windows 7 SP1 and Windows Embedded Standard 7 SP1 Microsoft updates are required for the support of SHA-256. Refer to Microsoft KB3033929 for more information about how to install this security update.
|Note DIAdem runs only with restrictions on the N or KN edition of Windows because the multimedia support is missing. You can obtain this as "Media Feature Pack" from Microsoft and install it later.|
Under Windows Server 2012 R2 you cannot play videos in DIAdem VIEW.
|Firewall||The firewall displays warnings while DIAdem installs and while DIAdem launches, for the following reasons: |
The usireg component executes during the installation of DataPlugins. The DataFinder, which you use for searching and navigating in files, then starts. When DIAdem launches, a DNS query determines whether to license locally or whether to use a license server.
If you want to be able to use all the DIAdem functions, National Instruments recommends that you select "Do not block" for all programs listed. This also applies when you want to evaluate DIAdem. Refer to ni.com/info under the info code winxpsp2 for more information.
|Windows User Rights||DIAdem and its components are basically executable under the pre-configured Microsoft Windows user accounts from User upwards. DIAdem must be installed with complete administrator rights. |
If you operate various DIAdem versions on one computer, you only have the entire range of functions in each version if you have administrator rights.
- Adobe Reader to display manual files
|ADCS||Automotive Diagnostic Command Set||>= 18.0|
|DAQmx driver||NI-DAQmx||>= 9.4|
|ECU MC||ECU Measurement and Calibration Toolkit||>= 18.0|
Very old commands and variables, which have been replaced by new technologies, are marked as obsolete in DIAdem. This means that these commands and variables are no longer supported in one of the upcoming DIAdem versions. On the DIAdem help page DIAdem»Searching for Obsolete Commands and Variables you can find a script which checks your scripts for obsolete identifiers.
If you install an earlier DIAdem version after you have installed the current DIAdem version, the PDF export of the earlier version might not function correctly. You can solve the issue by copying the files acfpdf*.* and cdintf*.dll from the current DIAdem program folder into the program folder of the earlier DIAdem version.
Installing DIAdem 2018 and DataFinder Server Edition 2015 or 2017 on the same computer might lead to DataFinder Server Edition 2015 or DataFinder Server Edition 2017 becoming inoperable.
If you have a parallel installation of DIAdem 2018 and DIAdem 2017, you cannot, in DIAdem 2017, use the DataFinder hierarchy preview, which you open in DIAdem SCRIPT through “Settings”TDM Server->DataFinder Hierarchy”.
From version 2018, DIAdem imports by default VBS DataPlugins in encrypted form. You can only import and then process a DataPlugin unencrypted if you select Import DataPlugin in the DataPlugin Settings dialog box.
The images you use in the Picture for Tree SUD property must have a minimum size of 16*16 pixels.
You cannot use VIs that require .NET assemblies from DIAdem through the LVRuntime object.

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 4.6.2, 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 4.6.2 separately before you install NI software.
For more information, refer to the following KnowledgeBase articles:
Microsoft Windows 10 is the latest version of the Windows operating system. Windows 10 features significant changes compared to previous versions. Windows 10 combines features from both Windows 7 and Windows 8. Moreover, the operating system introduces several new capabilities. For more information about NI support for Windows 10, visit ni.com/windows10.
When you install NI software on Microsoft Windows 8.1, you will notice a few additional tiles in the Apps view, including shortcuts to NI application software products such as NI LabVIEW, Measurement & Automation Explorer (NI MAX), and NI Launcher. For more information about NI support for Windows 8.1, visit ni.com/windows8.
