During the process of uninstalling and reinstalling labeiw, I always encounter some problems. Record the solutions so that I can find them easily when I encounter them.
Personal recommendation to uninstall
Use the uninstall software that comes with laview to uninstall, and the uninstall is relatively clean.
The first step to complete uninstallation
Start the uninstall software that comes with labview to uninstall. Generally, after completing this step, you can reinstall labview.
Second step of complete uninstall
If during the uninstallation process, due to some reasons, some functions may not be installed after installing labview. If encountered, check “Add/Remove Programs” to see if the entry remains: Go to Start>>Run and type “regedit”, go to HKEY_LOCAL_MACHINE/SOFTWARE/National Instruments/Common_Installer, delete it still showing in “Add/Remove Programs” Related registry keys for components in . NOTE: The keys will appear with similar names and a long numeric/letter code after the initial text. I also deleted an IVI service.

Completely uninstall finishing moves
- Theoretically, there should be no problem after reinstalling labview after the above operations. If there are still problems, delete all the registry entries containing National Instruments in the registry.
Some parts may not be deleted, but there will be no impact. Big, I deleted everything that could be deleted. - Delete the information related to labview in the environment variables, such as labview, National Instruments, etc.
- If there are some plug-ins that cannot be installed,
such as VIPM, delete all the ones related to vipm in the registry, and then there will be no problem after installation.

You should be ready to install your software. For the cleanest possible install, first install all of your application development software, such as LabVIEW, Measurement Studio, etc. Do a custom install, so that you can install just the application WITHOUT ANY DRIVERS. Reboot your PC when requested after each install. Even if the installer does not tell you to reboot, it would probably be a good idea to do so anyway. Now install your driver software and follow the associated user manuals. Some older non Plug -n-Play hardware must be installed before the driver. Download the latest versions of the drivers that support your hardware from our Drivers and Updates software library (link below), and install them one-by-one, rebooting after each install. 6. Finally, shut down and re-install your hardware.
