Installing LabWindows/CVI

Before Installation

• If you install the LabWindows/CVI Real-Time Module and device drivers with LabWindows/CVI 8.1, you must install these products in the following order:
  Do not install the device driver software when you are prompted to do so during the LabWindows/CVI 8.1 installation. You will be prompted to install the device driver software again during the LabWindows/CVI Real-Time Module installation.

• LabWindows/CVI 8.1

• LabWindows/CVI Real-Time Module

• Device driver software from the NI Device Drivers CD set
  

• When you install or activate LabWindows/CVI 8.1, your user account must have administrator privileges. When you run LabWindows/CVI for the first time after installation, your user account must have administrator privileges.

• You must explicitly select the Win32 SDK feature of the LabWindows/CVI installer to install the complete Windows SDK from the LabWindows/CVI Full Development System (FDS). Some Windows SDK header and import library files are included when you install the LabWindows/CVI Base Package. The Windows SDK help file is available only with the LabWindows/CVI FDS.

• The LabWindows/CVI installation includes the LabWindows/CVI 8.1 Run-Time Engine. This version overwrites previous versions of the run-time engine. After you install LabWindows/CVI 8.1, executables and DLLs created with previous versions of LabWindows/CVI automatically use the new LabWindows/CVI 8.1 Run-Time Engine.

• If you install LabWindows/CVI onto a network drive, you might encounter an error during installation that prevents files that the IVI Instrument Driver Wizard requires from being installed. This issue does not affect other functionality in LabWindows/CVI.

• If you have installed Microsoft Security Update 896358, you might not be able to view topics within the LabWindows/CVI Help if the file is on a network drive. To solve this issue, copy the .chm files that LabWindows/CVI installs to your local hard drive and launch them as normal.

• If you uncheck the top-level LabWindows/CVI feature in the installer feature tree, the installer installs some components that you cannot then uninstall. Therefore, National Instruments recommends that you leave the top-level LabWindows/CVI feature checked.

• The IVI Installer Creator and IVI Specific Driver Test Suite items are selected by default in the installer feature tree only if the IVI Compliance Package is installed. If the IVI Compliance Package is not installed, you can select these items, but you must then install the IVI Compliance Package from the NI Device Drivers CD set to use these features.
  

Running the Installation

• Insert the LabWindows/CVI CD into the CD drive. If the CD does not run automatically, open Windows Explorer, right-click the CD drive icon, and select AutoPlay.

• Select Install LabWindows/CVI on the National Instruments LabWindows/CVI screen.

• LabWindows/CVI prompts you to enter your user information. Select one of the following options:
  If you choose to enter a serial number, enter the serial number found on your Certificate of Ownership card. LabWindows/CVI automatically uses this serial number when you run the NI Activation Wizard.

• Install this product using the following serial number

• Install this product for evaluation
  

• Continue to follow the instructions on the screen.
  

Activating LabWindows/CVI

• Select the Automatically activate through a secure Internet connection option and click Next. Your computer must be connected to the Internet for this option to work. If you do not have Internet access on your computer, refer to the LabWindows/CVI Release Notes.

• The serial number should be automatically entered for you. If not, enter the serial number found on your Certificate of Ownership card and click Next.

• Fill in the necessary information and click Next.

• Check the option if you would like to receive a confirmation email of your activation and click Next.

• After a brief moment, you should receive a message indicating whether LabWindows/CVI has been activated or not. Enter or verify your serial number. Click Next.

• Continue to follow the instructions on the screen.

• When you successfully activate LabWindows/CVI, click Finish. LabWindows/CVI will then display a window indicating when this license will expire.
  

After Installation

• Installing LabWindows/CVI in a New Directory—If you installed driver or toolkit software for a previous version of LabWindows/CVI and you install LabWindows/CVI 8.1 in a new directory, you must uninstall and reinstall the LabWindows/CVI portion of the driver or toolkit software.
  

Known Issues

• Setting the Compatibility Mode for Real-Time DLLs—When you create a DLL to run on a real-time target, you must use the Visual C/C++ compatibility mode. The Borland C/C++ compatibility mode is not supported for real-time DLLs.

• Projects Built Using LabWindows/CVI Beta—If you created any projects using the LabWindows/CVI Beta, you must rebuild the project in LabWindows/CVI 8.1.

• Using the LabWindows/CVI Conversion Wizard in Visual Studio 2005—Microsoft Visual Studio 2005 removed support for the single-threaded version of its C library. Therefore, you must configure your project's linker settings to ignore directives to use the single-threaded C library. In Visual Studio, select Project»Properties and expand the properties tree to the Configuration Properties»Linker»Input item. Add libc to the Ignore Specific Library option. Refer to the I Receive Linker Errors When Using LabWindows/CVI-Generated Static Libraries and Object Files in Microsoft Visual Studio 2005 KnowlegeBase article for more information.

• Updating an Existing Distribution—The LabWindows/CVI distribution creation feature no longer provides the option to include .obj files for both compatible compilers. If you convert an existing distribution that has this option enabled, LabWindows/CVI includes the .obj files only for the current compatible compiler in the updated distribution.

• Using the NI Instrument I/O Assistant—The Instrument I/O Assistant 2.0, which is included in the NI Device Drivers CD set packaged with LabWindows/CVI, generates LabWindows/CVI code that is not backward compatible with code that previous versions of the Instrument I/O Assistant generated. If you run code generated with the Instrument I/O Assistant 2.0 with an existing application, the code in that application might not compile.

• Uninstalling LabWindows/CVI—If you have multiple versions of LabWindows/CVI installed and you uninstall one of the versions, the remaining installation will be missing its file associations, and its automation capabilities will not function properly. To fix this problem, perform a repair installation of the remaining LabWindows/CVI version.

• Making Backup .uir Files—If you have been using LabWindows/CVI 7.1 or earlier, make backup copies of your .uir files. Once you save .uir files in LabWindows/CVI 8.1, the .uir files are no longer compatible with versions 7.1 or earlier. You cannot load .uir files that you have saved in LabWindows/CVI 8.1 in LabWindows/CVI 7.1 or earlier.
  
  You can save .uir files you create or load in LabWindows/CVI 8.1 in LabWindows/CVI 7.1 format. Select File»Save .uir As and specify LabWindows/CVI 7.1 User Interface (*.uir) for the Save as type option. If you save a user interface with features that were added in LabWindows/CVI 8.0 and later, those features are removed when you save the file in 7.1 format.

• Using Microsoft Excel as an ActiveX Control—If you develop an application that uses Excel as an ActiveX control on a LabWindows/CVI user interface panel, make sure that a separate instance of Excel is not running simultaneously. Otherwise, programmatic calls to the Excel control might not work as expected after the separate Excel application terminates.

• Navigating the Tools Library Topics in the LabWindows/CVI Help—If you click a link from a topic in the Tools Library section of the LabWindows/CVI Help or from the toolslib function panel help, you cannot use the Back button in the help viewer toolbar to return to the original topic.

• Analysis Function Behavior Changes—The updated Advanced Analysis Library functions are backward compatible with the previous versions. However, the following function behavior has changed from LabWindows/CVI 7.1 to LabWindows/CVI 8.x:
  
  

• SVD and CxSVD—The following formula defines the SVD factorization of an n-by-m matrix A: A = USVT.
  
  In LabWindows/CVI 7.1 and earlier, U is an orthogonal matrix of dimensions n-by-m. In LabWindows/CVI 8.x and later, U is an orthogonal matrix of dimensions n-by-min(n, m).
  
  In LabWindows/CVI 7.1 and earlier, V is an orthogonal matrix of dimensions m-by-m. In LabWindows/CVI 8.x and later, V is an orthogonal matrix of dimensions m-by-min(n, m).
  
  In LabWindows/CVI 7.1 and earlier, S is a diagonal matrix of dimensions m-by-m. In LabWindows/CVI 8.x and later, S is a diagonal matrix of dimensions min(n, m)-by-min(n, m).
  
  In LabWindows/CVI 7.1 and earlier, CxSVD has the following requirement: If numberOfRows (n) < numberOfColumns (m), you must allocate m*m*sizeof(ComplexNum) bytes of memory to the input matrix and the U orthogonal matrix. LabWindows/CVI 8.x no longer has this requirement.

• Lu and CxLU—In LabWindows/CVI 7.1 and earlier, if the input matrix is singular, the functions stop the decomposition and return SingularMatrixErr. In LabWindows/CVI 8.x and later, if the input matrix is singular, the functions complete the decomposition and return SingularMatrixWarn. In this case, there are one or more zero elements along the diagonal of U.

• CxTrace—CxTrace accepts only a square matrix. In LabWindows/CVI 7.1 and earlier, the function requires both the number of rows and the number of columns as input parameters. In LabWindows/CVI 8.x and later, matrixSize specifies both the number of rows and the number of columns. The numberOfColumns parameter in LabWindows/CVI 7.1 and earlier is a reserved parameter in LabWindows/CVI 8.x. This parameter is not referenced in the function.

• ConditionNumber and CxConditionNumber—In LabWindows/CVI 7.1 and earlier, these functions return NaN for singular input matrices. In LabWindows/CVI 8.x and later, these functions return Inf for singular input matrices.

• GenLSFit—In LabWindows/CVI 8.x and later, GenLSFit calculates the mean squared error as the weighted mean square error, which differs from the prior implementation of the function.
