The following steps document the correct procedure to repair or uninstall National Instruments software products under Windows XP, Windows Vista, or Windows 7.
Note: If you are using NI Package Manager (NIPM) for products such as LabVIEW NXG or DAQExpress, please use this article instead. If you are unsure which method you are using, please continue below and review at step 6.
Note: Performing a repair installation of any National Instruments software product will reinstall any missing or corrupt files, registry keys, or shortcuts. Any preferences stored in the registry may be reset to default values, so take note of any custom program settings you may have configured.
