  • 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. These versions do not interfere and can operate alongside each other.
  • In addition to different versions, you can have both 32-bit and 64-bit versions of LabVIEW on the same machine.
  • You can open LabVIEW Projects and VIs in an earlier version without affecting other installations. To switch to an earlier version, simply launch the project or VI in the desired LabVIEW version, then use File >> Open to open the desired project or VI. The VI will be converted to the appropriate format automatically.
  • ​​​​​​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 can have its own toolkits and modules.

Additional Information

  • When running various versions, you will want to check that your desired versions are compatible with your operating system
  • 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:
