LabVIEW 8.2.1 Readme for Windows

Supported Platforms

Installing LabVIEW 8.2.1

Installing Another Language Version

Installing LabVIEW Silently

Licensing

Known IssuesInstallation

• If you uninstall LabVIEW 8.2.1 and a previous version of LabVIEW remains on the system, the previous version of LabVIEW might try to repair itself the next time you open it. The repair process might remove any patches you installed for that version of LabVIEW. Make sure to reinstall any patches you have on the system after the repair finishes. Refer to the KnowledgeBase at ni.com for more information about this issue.

• If you have Windows XP Service Pack 2 or Windows Vista installed, a Security Alert dialog box appears when you launch LabVIEW or the NI Example Finder for the first time. If you select the Keep blocking this program option, the LabVIEW VI Server, LabVIEW Web Server, and any server written in LabVIEW cannot accept incoming connections from a remote computer. Select the Unblock this program, despite the security risk option to configure your computer to launch LabVIEW without any changes in functionality. Refer to the KnowledgeBase at ni.com for more information about correcting this problem.
  

VIs, Express VIs, and Functions

• The links to subVIs from the ni.com for more information about correcting this problem.

• If you create a new, untitled VI while using the Storage VIs, the numbering of the untitled VI might be inconsistent.

• The Storage VIs do not support the extended-precision, floating-point data type. If you wire this data type to a Storage VI, LabVIEW returns a compiler error when you run the VI.

• The Delete Data VI does not work with .tdm file, the size of the file does not change, but you cannot access the data you try to delete.

• The Sound File Read VI uses large amounts of memory to read an entire .wav file piece by piece rather than in one large file.

• The Array instance of the Sound Output Set Volume VI does not use the volume input to set the volume on a per-channel basis. Instead, this VI uses the first element of the volume input as the sound level for all channels.

• The Read From Measurement File Express VI returns an error if you call it on the same file multiple times, which makes using this Express VI in a subVI problematic.

• If the Database Connectivity Toolkit is installed, you cannot place the Database Variant To Data function on the block diagram. Refer to the KnowledgeBase at x7FFFFFFF as an unsigned, 32-bit integer to a Formula Node, LabVIEW coerces the value to 0.

• If you register an ActiveX event, you must unregister the event explicitly. Otherwise, memory leaks might occur because the ActiveX control does not know that the client has disconnected.

• When you select Tools»Compare»Compare VIs and use the Compare VIs dialog box, LabVIEW does not display differences between values of cluster constants.
  

Environment

• A blue field does not surround the palette icons for Express VIs from LabVIEW 7.x and earlier that you open in LabVIEW 8.2.1. For example, if you use a LabVIEW 7.1 toolkit in LabVIEW 8.2.1, a blue field does not surround the icons for Express VIs on the toolkit palette. You must mass compile the Express VIs to display the blue field around the icons.

• If you define a custom run-time menu for a control and you save that run-time menu with the control, you cannot localize the run-time menu. As a workaround, you can save the custom run-time menu to an external file and point the control to that file, or you can build the run-time menu dynamically with localized strings.

• LabVIEW does not correctly hide subpalette menus that belong to locked project libraries.

• When you print the VI Hierarchy window, LabVIEW does not print the VI labels.
  

LabVIEW MathScript

• If you select File»Save for Previous Version and save a VI that contains a MathScript Node for LabVIEW 8.0, the VI is broken when you load it in LabVIEW 8.0. To correct this problem, load the VI in LabVIEW 8.0 and then modify the script in the MathScript Node. For example, add and remove a space. Then click the block diagram outside of the MathScript Node. When you click the Run button, the VI runs correctly.

• MathScript does not support string inputs that use LaTeX syntax.

• If you mass compile VIs last saved in a previous version of LabVIEW and the VIs contain MathScript Nodes, LabVIEW might return error messages, but LabVIEW compiles and saves the VIs correctly.

• If a LabVIEW MathScript contains a gca, get, or ni.com for more information about correcting this problem.

• If you rename a parent class while any child classes are in memory, LabVIEW does not record the mutation history of the class correctly. LabVIEW resets any flattened data or non-default data in memory to the default value. To avoid losing data, rename a class only when it is not in memory. Refer to the KnowledgeBase at http protocol with the DataSocket VI and functions in LabVIEW-built shared libraries.

• You cannot use front panel DataSocket data binding with fixed-sized arrays.

• If you use the DataSocket Server Manager to create a Boolean object, the DataSocket Server Manager converts the Boolean object to numeric data in the configuration file.
  

Shared Variables

• You can read from and write to private single-process shared variables.

• If you open a VI that contains a shared variable from a zip file, LabVIEW displays a file dialog box indicating that it cannot find the file for the global VI associated with the shared variable. Click the Cancel button to recreate the global VI.

• LabVIEW fails to deploy all shared variables in a library if one shared variable has an invalid binding. To correct this problem, either delete the shared variable that has an invalid binding or unbind the shared variable.

• If you select File»Save for Previous Version and save a VI that contains a Shared Variable node for LabVIEW 8.0, the VI might not return correct results. If you save the VI for LabVIEW 8.0.1, the VI returns correct results. Refer to the KnowledgeBase at ni.com for more information about using remote panel servers with built applications.

• If you have more than one Ethernet card, Logos is automatically assigned to the primary Ethernet card. To assign Logos to a different Ethernet card, switch the Ethernet cards.

• The maximum size of datalog files is 2 GB.

• .NET type definitions do not correctly update when you change the related assembly.

• If you use the Edit Items page of the Enum Properties dialog box to edit an enumerated type control that contains a large amount of items, LabVIEW 8.2.1 might perform slower than LabVIEW 8.0. To avoid this problem, use the Labeling tool to add or edit items directly from the front panel. Refer to the Adding Items to Enumerated Type Controls topic in the LabVIEW Help for more information about adding items to enumerated type controls.
  

Windows Vista

• For compatibility reasons, the LabVIEW installation process enables write permissions for the -start and net start and .tdm and .tdms file into the new .tdm file format.

• The System Requirements section on the Advanced page of the Installer Properties dialog box includes the option Windows Vista and later. Use this option if you want to specify that users have Microsoft Windows Vista or a later version to run the installer.

• The Create Instrument Driver Project wizard includes a progress bar so you can view the status of the instrument driver project as LabVIEW builds it. You can cancel the operation by clicking the Cancel button.

• The default value for the Cache VIs component of the Mass Compile dialog box changed from 5 to 10. Also, caching VIs is enabled by default.

• In LabVIEW 8.0 or earlier, the value for the Priority input of a Timed Loop must be a positive integer between 1 and 2,147,480,000. In LabVIEW 8.2.x, the value for the Priority input must be a positive integer between 1 and 65,535.

• To create a new VI or project from the LabVIEW MathScript Window, you first must return to the Getting Started window by selecting View»Getting Started Window.

• You must use NI Spy 2.3 or later in LabVIEW 8.x. NI Spy 2.4 is available on the National Instruments Device Drivers CD.

• You must use the LabVIEW Report Generation Toolkit 1.1.1 or later in LabVIEW 8.2.1. Refer to the National Instruments Web site to access the Upgrade Advisor and order the Report Generation Toolkit 1.1.1 or later.

• You must use Measurement Studio 8.0 or later with LabVIEW 8.2.x. Refer to the National Instruments Web site to access the Upgrade Advisor and order Measurement Studio 8.0.

• LabVIEW initializes a Shared Variable node the first time you run a VI that contains that node.

• In LabVIEW 7.x and earlier, LabVIEW enables debugging automatically for new VIs. If you then make a VI reentrant by selecting File»VI Properties, selecting Execution from the pull-down menu, and placing a checkmark in the Reentrant execution checkbox, LabVIEW automatically removes the checkmark from the Allow debugging checkbox. In LabVIEW 8.x, LabVIEW does not automatically remove the checkmark from the Allow debugging checkbox.

• A .NET or ActiveX property that returns a reference to a class outside the current type library cannot be made into a dotted property. When you view the property in the Class Browser window, a blue glyph does not appear next to the property name in the Properties and Methods list.

• LabVIEW supports smooth scrolling, or scrolling by pixels, on the front panel and block diagram of a VI.

• Select File»Close in a file with unsaved changes to display the Save changes before closing? dialog box. Select File»Close All to display the Save changes and Close All? dialog box.

• You can access LabVIEW data files from DIAdem regardless of the format in which you stored those data files.

• If you configure source control in LabVIEW, LabVIEW does not report an error when you save a VI to a directory outside the SCC specification.

• In LabVIEW 7.x and earlier, if you wire dynamic data to a waveform-based polymorphic VI that has Automatic selected in the polymorphic VI selector, LabVIEW selects the 1-channel instance. In LabVIEW 8.x, LabVIEW selects the N-channel instance. The N-channel instance returns arrays of measurement data instead of a single measurement, so VIs that use a waveform-based polymorphic VI might be broken in LabVIEW 8.x. If you want to process only the first signal in the dynamic data, you must manually select the 1-channel instance in the polymorphic VI selector.

• You must use an application reference when you use VI server properties and methods in one application instance, and you want to interact with a different application instance. It is not always obvious that VIs are running in different application instances. For example, each LabVIEW project has its own application instance, and each target within a project has its own application instance. LabVIEW also creates a main application instance, which contains open VIs that are not part of a project and VIs that you did not open from a project. In addition, LabVIEW opens user VIs you place in the labviewproject, and <font face="" "="" style="margin: 0px; padding: 0px; overflow-wrap: break-word;">labviewwizard directories in a private application instance. If you are unsure whether you are interacting with a different application instance, use an application reference.
