You can have multiple versions of LabVIEW installed on the same computer. These versions can operate alongside each other. This is true for:
- LabVIEW Release Versions: LabVIEW yearly releases can be installed on the same machine and will not affect each other.
- Bitness: You can have both 32-bit and 64-bit versions of LabVIEW on the same machine.
Different service pack versions (SP1, etc.) or the original can not be installed side-by-side as they are installed in the same folder.
(For example, installing LV 2018 SP1 will override the files of LV 2018, because the installation path for both is C:\Program Files (x86)\National Instruments\LabVIEW 2018
If you have LabVIEW code written in previous versions and install a later version, you are still able to open your code in previous versions.
You do not need to uninstall previous versions of LabVIEW you already have on your machine to install a newer version of LabVIEW on the same machine. Each version of LabVIEW will be installed separately and can have its modules. Note:
For a breakdown of the considerations you should take into account when looking into using different versions of LabVIEW, please see Recommendations When Using Multiple Versions of LabVIEW and LabVIEW Toolkits
