  • LabVIEW

Issue Details

  • Can a later version of LabVIEW be installed without affecting the existing LabVIEW installation?
  • Can VIs still be opened using an earlier LabVIEW version after installing the later version? 
  • How can I properly install a newer version of LabVIEW if I already have previous versions of LabVIEW installed on the same machine?

Solution

You can have multiple versions of LabVIEW installed on the same computer, it also can be a 32 bits version and a 64 bits version installed together. Make sure that all versions of LabVIEW are compatible with the computer's operating system

You can open LabVIEW Projects and VIs in an earlier version without affecting other installations. To switch between versions, simply launch the project or VI in the desired LabVIEW version. The VI will be converted to the appropriate format automatically.

Additional Information

  • You do not need to uninstall previous versions of LabVIEW you already have on your machine in order to install a newer version of LabVIEW on the same machine. Each version of LabVIEW will be installed separately and have its own toolkits and modules.
  • If you open a project or VI without manually selecting the LabVIEW program, LabVIEW will automatically launch in the version that was last used. For example, if the last open instance of LabVIEW was 2012 and you try to open a LabVIEW 2017 VI, the LabVIEW will attempt to open the VI in the LabVIEW 2012 environment. In this case, this will result in a version compatibility error. Conversely, if the last open instance of LabVIEW was 2017 and you try to open a LabVIEW 2012 VI, LabVIEW will open the VI in the LabVIEW 2017 environment. If you make any changes to the VI and save or run it, it will be compiled to be a LabVIEW 2017 VI.

You will also want to take into consideration driver and toolkit compatibility. For a more detailed breakdown of the considerations you should take into account when looking into using different versions of LabVIEW please see the following two documents:
