LabWindows/CVI Programmer Reference Manual for a descr iption of the LabW indo ws/CVI

Run-time Engine.

Note The LabWindows/CVI 5.0 Run-time Engine for Windows 95/NT overwrites

previous versions of the Run-time Engine. Thus, LabWindows/CVI 4.x-generated

executables and DLLs use the new LabWindows/CVI 5.0 Run-time Engine. In

addition, the LabWindows/CVI 4.x Create Distribution Kit feature includes the

LabWindows/CVI 5.0 Run-time Engine instead of the LabWindows/CVI 4.x

Run-time Engine in generated distribution kits.

Installing the VISA Library

You need the VISA Library to use the new instrument driver standard the VXIplug&play

Systems Alliance accepts. VISA stands for Virtual Instrument Software Architecture.

NI-VISA is installed as part of the LabWindows/CVI disk and CD-ROM installations for

Windows 95/NT. NI-VISA must be installed separately for LabWindows/CVI for

Windows 3. x.

Installing the IVI Engine

You need the IVI Engine to use IVI (Intelligent Virtual Instruments) drivers on a system. The

IVI Engine is installed as part of LabWindows/CVI for Windows 95/NT and Windows 3.x.

LabWindows/CVI for Windows 95/NT includes a separate set of IVI Engine distribution

disks or a directory on the CD-ROM that has its own installation program so you can make

copies for distribution with your application. On Windows 3.x, the IVI Engine is a static

library that is linked into your application.
