'''LabWindows/CVI''' (CVI is short for [[C (programming language)|C]] for [[Engineering:Virtual instrumentation|Virtual Instrumentation]]) is an ANSI C programming environment for test and measurement developed by [[National Instruments]]. The program was originally released as LabWindows for [[Engineering:DOS|DOS]] in 1987, but was soon revisioned (and renamed) for the [[Software:Microsoft Windows|Microsoft Windows]] platform. The current version of LabWindows/CVI (commonly referred to as CVI) is 2020.

LabWindows/CVI uses the same libraries and data-acquisition modules as the better known National Instrument product [[Software:LabVIEW|LabVIEW]] and is thus highly compatible with it.

[[Software:LabVIEW|LabVIEW]] is targeted more at domain experts and scientists, and CVI more towards software engineers that are more comfortable with text-based linear languages such as [[C (programming language)|C]].

== Release history ==
Starting with LabWindows/CVI 8.0, major versions are released around the first week of August, to coincide with the annual National Instruments conference NI Week, and followed by a bug-fix release the following February.

In 2009, National Instruments started to name the releases after the year in which they are released. The bugfix is called a Service Pack (for instance, the ''2009 Service Pack 1'' release was published in February 2010).<ref>[http://www.ni.com/product-documentation/6609/en/ LabWindows™/CVI™ Release Information]</ref>
